Abstract:

One of the reasons of dramatic situation with tuberculosis in Russia is untimely diagnostics of tuberculosis. The aim of the study was to identify the causes of diagnostic mistakes when we deal with disseminated pulmonary tuberculosis at current stage and to modernize the diagnostic process. The analysis of the diagnostic activity of the consultative diagnostic center of Central Tuberculosis Research Institute of Russian Academy Medical Sciences for 2011 was performed with special attention on the results of the survey of 505 patients with pulmonary dissemination. The frequency of discrepancies of disseminated pulmonary tuberculosis diagnostics was 96,1%. Based on the studies carried out the main causes diagnostic mistakes in patients with disseminated pulmonary tuberculosis were determined. New directions of improving of tuberculosis diagnostics were developed: overall high-technology examination of patient, adherence to the diagnostic procedure, developed by consultative diagnostic center of Central Tuberculosis Research Institute(CTRI), timely performing fiber-optic bronchoscopy with complex biopsy and diagnostic surgery procedures, further training of primary health care doctors. Implementation of proposed activities will significantly (by 3–5 times) reduce the time for diagnostics of respiratory system disease.

Abstract:

The paper represents the mathematical model for diagnostics of supercapacitors. The research objectives are the problem of determining a supercapacitor technical condition during its operation. The general reliability of diagnostics is described as the methodological and instrumental reliabilities of diagnostics. The instrumental diagnostic reliability of supercapacitor includes the probabilities of errors of the first and second kind, α and β respectively. The methodological approach to increasing the reliability of supercapacitor diagnostic has been proposed, in terms of multi-parameter supercapacitor diagnostic by applying nonlinear, frequency dependent mathematical models of supercapacitors that take into account nonlinearity, frequency dispersion of parameters and the effect of transient processes in supercapacitors. The more frequencies, operating voltages and currents are applied in the supercapacitor diagnostics, the more methodological reliability of diagnostics will increase in relation to the methodological reliability of supercapacitor diagnostics when only one frequency, voltage and current are applied.

Abstract:

Access to quality-assured, accurate diagnostics is critical to ensure that the 2021–2030 neglected tropical disease (NTD) road map targets can be achieved. Currently, however, there is limited regulatory oversight and few quality assurance mechanisms for NTD diagnostic tools. In attempting to address such challenges and the changing environment in regulatory requirements for diagnostics, a landscape analysis was conducted, to better understand the availability of NTD diagnostics and inform future regulatory frameworks. The list of commercially available diagnostics was compiled from various sources, including WHO guidance, national guidelines for case detection and management, diagnostic target product profiles and the published literature. The inventory was analyzed according to diagnostic type, intended use, regulatory status, and risk classification. To estimate the global need and size of the market for each type of diagnostic, annual procurement data were collected from WHO, procurement agencies, NGOs and international organizations, where available and global disease prevalence. Expert interviews were also conducted to ensure a better understanding of how diagnostics are procured and used. Of 125 diagnostic tools included in this analysis, rapid diagnostic tools accounted for 33% of diagnostics used for NTDs and very few diagnostics had been subjected to regulatory assessment. The number of tests needed for each disease was less than 1 million units per annum, except in the case of two diseases, suggesting limited commercial value. Despite the nature of the market, and presumed insufficient return on commercial investment, acceptable levels of assurance on performance, quality and safety of diagnostics are still required. Priority actions include setting up an agile, interim, stepwise risk assessment mechanism, in particular for diagnostics of lower risk, in order to support national NTD programmes and their partners with the selection and procurement of the diagnostics needed to control, eliminate and eradicate NTDs.

Abstract:

A review of recent developments in intense ion beam diagnostics used in the international light ion inertial confinement fusion (ICF) programs will be presented. These developments have occurred in each of the several generic classes of diagnostics, namely, imaging diagnostics, particle spectrograph diagnostics, nuclear activation, and visible spectroscopy. Critical beam parameters measured by the new diagnostics include spatial profile, absolute number, species, anode plasma temperature and density, voltage, current density, and power density. A unique feature of most of these diagnostics is that they are capable of operating in hard (multi-MeV) X-ray (bremsstrahlung) backgrounds of some 109–1011 rad/s. The operating principles of each diagnostic will be summarized in the paper with examples of how the diagnostics may be integrated together to form a complete diagnostic system. The paper will close with a discussion of two new data acquisition systems that have been developed for intense beam diagnostics.

Abstract:

The operable state of a system is maintained during operation, which requires knowledge of the system’s state. Technical diagnostics, as a process of accurately obtaining information about the system state, becomes a crucial stage in the life cycle of any system. The study deals with the relevant problem of uncertainty quantification of imperfect diagnostics. We considered the most general case when the object of diagnostics, the diagnostic tool, and the human operator can each be in one of the many states. The concept of a diagnostic error is introduced, in which the object of diagnostics is in one of many states but is erroneously identified as being in any other state. We derived the generalized formulas for the probability of a diagnostic error, the probability of correct diagnosis, and the total probability of a diagnostic error. The proposed generalized formulas make it possible to determine the probabilistic indicators of diagnosis uncertainty for any structures of diagnostics systems and any types of failures of the diagnostic tool and human operator. We demonstrated the theoretical material by computing the probabilistic indicators of diagnosis uncertainty for an aircraft VHF communication system and fatigue cracks in the aircraft wings.

Abstract:

The paper describes the determination of useful vibration spectrum components during strength tuning of gas turbine engine by the example of diagnostics of defects of bearing collars. New diagnostics criterion is proposed and used in diagnostics method. The usage of this method allows defining the location of a defect in early stages by transformation of informative diagnostic components of a signal masked by noise in vibration spectrum. Implementation of proposed diagnostics method makes diagnostic components discontinuous (not diffused by frequency). It simplifies the identification of diagnostic components in vibration spectrum in comparison with traditional methods of processing and analysis of dynamic signals.

Abstract:

Aim: Thorough diagnostics are a prerequisite for the optimal treatment of Alzheimer's disease (AD). Biomarker-based diagnostics are standard in academia, data on practitioners' diagnostic workups is scarce. Materials & methods: Surveys in German and US healthcare providers (HCP) were conducted regarding diagnostics in presumed AD patients. A subsample of 153 German and 88 US professionals was analyzed in detail. Results: Fewer German physicians conduct AD diagnostics themselves compared with US colleagues (67% vs 99%; p < 0.0001). German doctors more often order diagnostics at other institutions (65% vs 45%; p < 0.005). No significant differences were found regarding the type of diagnostics ordered at other institutions. Conclusion: Diagnostic routines for suspected AD patients differ between German and US–American healthcare providers.

Abstract:

INTRODUCTION: An alternator unit is a necessary unit in a vehicle, as it provides all the consumers with electricity. Therefore, the operation capability of the whole vehicle depends on the alternator units operational state. The issue of the diagnostics of a vehicle alternator unit by means of determination of alternator phases windings active resistance is addressed. AIM: Improvement of diagnostics informativity by means of voltage controllers with a self-diagnostic function. METHODS: It is proposed to perform the alternator unit diagnostics without dismantling or disassembly by means of plugging to the diagnostic points. RESULTS: The existing and known methods of vehicle alternator unit diagnostics with embedded diagnostic tools and with use of external diagnostic tools were analyzed. The method of diagnostics of phase winding active resistance with use of reference resistance was proposed. The algorithm of implementation of the proposed method was suggested. The recommendations for use of the proposed method were given. CONCLUSIONS: The proposed diagnostics method can be used in engine control units or by technicians of maintenance stations during the alternator unit maintenance without dismantling or disassembly.

Abstract:

Abstract We provide an overview of ITER beam aided diagnostics, including the motional Stark effect (MSE) and charge exchange recombination spectroscopy (CXRS). ITER presents several unique challenges to plasma diagnostics in general and beam-aided diagnostics in particular. The large size, long pulse, and DT operation drives much of the diagnostic design. This in turn has driven a significant R&D effort concerning the maintenance of plasma facing mirrors with sufficient reflectivity to maintain the utility of the diagnostic. In the case of MSE a new approach utilizing spectral splitting will be pursued instead of the conventional polarimetry approach due to the difficulty of maintaining and calibrating the polarizations properties of the plasma facing mirror.

Abstract:

The Lancet Commission on Diagnostics highlighted a huge gap in access to diagnostic testing even for basic tests, particularly at the primary care level, and emphasised the need for countries to include diagnostics as part of their universal health coverage benefits packages. Despite the poor state of diagnostic-related services in low-income and middle-income countries (LMICs), little is known about the extent to which diagnostics are included in the health benefit packages. We conducted an analysis of seven Asian LMICs—Cambodia, India, Indonesia, Nepal, Pakistan, Philippines, Viet Nam—to understand this issue. We conducted a targeted review of relevant literature and applied a health financing framework to analyse the benefit packages available in each government-sponsored scheme. We found considerable heterogeneity in country approaches to diagnostics. Of the seven countries, only India has developed a national essential diagnostics list. No country presented a clear policy rationale on the inclusion of diagnostics in their scheme and the level of detail on the specific diagnostics which are covered under the schemes was also generally lacking. Government-sponsored insurance expansion in the eligible populations has reduced the out-of-pocket health payment burden in many of the countries but overall, there is a lack of access, availability and affordability for diagnostic-related services.

Abstract:

Abstract BACKGROUND During the past decade, breakthroughs in sequencing technology and computational biology have provided the basis for studies of the myriad ways in which microbial communities (“microbiota”) in and on the human body influence human health and disease. In almost every medical specialty, there is now a growing interest in accurate and replicable profiling of the microbiota for use in diagnostic and therapeutic application. CONTENT This review provides an overview of approaches, challenges, and considerations for diagnostic applications borrowing from other areas of molecular diagnostics, including clinical metagenomics. Methodological considerations and evolving approaches for microbiota profiling from mitochondrially encoded 16S rRNA-based amplicon sequencing to metagenomics and metatranscriptomics are discussed. To improve replicability, at least the most vulnerable steps in testing workflows will need to be standardized and continuous efforts needed to define QC standards. Challenges such as purity of reagents and consumables, improvement of reference databases, and availability of diagnostic-grade data analysis solutions will require joint efforts across disciplines and with manufacturers. SUMMARY The body of literature supporting important links between the microbiota at different anatomic sites with human health and disease is expanding rapidly and therapeutic manipulation of the intestinal microbiota is becoming routine. The next decade will likely see implementation of microbiome diagnostics in diagnostic laboratories to fully capitalize on technological and scientific advances and apply them in routine medical practice.

Abstract:

One of the main challenges in the development of a plasma diagnostic and control system for DEMO is the need to cope with unprecedented radiation levels in a tokamak during long operation periods. A list of diagnostics required for plasma control has been developed during the pre-conceptual design phase. Different approaches are proposed for the integration of these diagnostics in DEMO: in equatorial and upper ports, in the divertor cassette, on the inner and outer surfaces of the vacuum vessel and in diagnostic slim cassettes, a modular approach developed for diagnostics requiring access to the plasma from several poloidal positions. According to each integration approach, diagnostics will be exposed to different radiation levels, with a considerable impact on their design. This paper provides a broad overview of the radiation environment that diagnostics in DEMO are expected to face. Using the water-cooled lithium lead blanket configuration as a reference, neutronics simulations were performed for pre-conceptual designs of in-vessel, ex-vessel and equatorial port diagnostics representative of each integration approach. Flux and nuclear load calculations are provided for several sub-systems, along with estimations of radiation streaming to the ex-vessel for alternative design configurations. The results can be used as a reference by diagnostic designers.

Abstract:

Caries is a process of destruction of hard tooth tissues, which occurs with the participation of cariogenic bacteria in the oral cavity (in the composition of dental plaque), as well as food residues processed by them. The organic acids produced by the bacteria gradually destroy first the enamel of the tooth and then the underlying dentin. As a result, a carious cavity is formed in the tooth, the walls of which are filled with soft decay of decaying dental tissues and a large number of cariogenic bacteria. The following article looks into the reasons leading to dental problems, its diagnostics and treatment methods.

Abstract:

Diagnostics are fundamental for successful outbreak containment. In this supplement, ‘Diagnostic preparedness for WHO Blueprint pathogens’, we describe specific diagnostic challenges presented by selected priority pathogens most likely to cause future epidemics.Some challenges to diagnostic preparedness are common to all outbreak situations, as highlighted by recent outbreaks of Ebola, Zika and yellow fever. In this article, we review these overarching challenges and explore potential solutions. Challenges include fragmented and unreliable funding pathways, limited access to specimens and reagents, inadequate diagnostic testing capacity at both national and community levels of healthcare and lack of incentives for companies to develop and manufacture diagnostics for priority pathogens during non-outbreak periods. Addressing these challenges in an efficient and effective way will require multiple stakeholders—public and private—coordinated in implementing a holistic approach to diagnostics preparedness. All require strengthening of healthcare system diagnostic capacity (including surveillance and education of healthcare workers), establishment of sustainable financing and market strategies and integration of diagnostics with existing mechanisms. Identifying overlaps in diagnostic development needs across different priority pathogens would allow more timely and cost-effective use of resources than a pathogen by pathogen approach; target product profiles for diagnostics should be refined accordingly. We recommend the establishment of a global forum to bring together representatives from all key stakeholders required for the response to develop a coordinated implementation plan. In addition, we should explore if and how existing mechanisms to address challenges to the vaccines sector, such as Coalition for Epidemic Preparedness Innovations and Gavi, could be expanded to cover diagnostics.

Abstract:

There is a large gap between diagnostic needs and diagnostic access across much of sub-Saharan Africa (SSA), particularly for infectious diseases that inflict a substantial burden of morbidity and mortality. Accurate diagnostics are essential for the correct treatment of individuals and provide vital information underpinning disease surveillance, prevention, and control strategies. Digital molecular diagnostics combine the high sensitivity and specificity of molecular detection with point-of-care format and mobile connectivity. Recent developments in these technologies create an opportunity for a radical transformation of the diagnostic ecosystem. Rather than trying to emulate diagnostic laboratory models in resource-rich settings, African countries have the potential to pioneer new models of healthcare designed around digital diagnostics. This article describes the need for new diagnostic approaches, highlights advances in digital molecular diagnostic technology, and outlines their potential for tackling infectious diseases in SSA. It then addresses the steps that will be necessary for the development and implementation of digital molecular diagnostics. Although the focus is on infectious diseases in SSA, many of the principles apply to other resource-limited settings and to noncommunicable diseases.

Abstract:

Point-of-care (POC) diagnostic services are commonly associated with pathology laboratory services. This issue presents a holistic approach to POC diagnostics services from a variety of disciplines including pathology, radiological and information technology as well as mobile technology and artificial intelligence. This highlights the need for transdisciplinary collaboration to ensure the efficient development and implementation of point-of-care diagnostics. The advent of the novel coronavirus 2019 (COVID-19) pandemic has prompted rapid advances in the development of new POC diagnostics. Global private and public sector agencies have significantly increased their investment in the development of POC diagnostics. There is no longer a question about the availability and accessibility of POC diagnostics. The question is “how can POC diagnostic services be integrated into health services in way that is useful and acceptable in the COVID-19 era?”.

Abstract:

Proposed work is the fourth in the cycle, therefore, the diagnostic problem is formulated for the case ofexact trajectorial measurements, the diagnostic theorem is stated and proved, and two diagnostic algorithmsthat follow from this theorem are presented. Techniques for an a priori counting of constants, which shouldbe stored in a program for the computer-aided diagnostics whenever the first diagnostic algorithm is used,and other algorithmic parameters are considered. If the second algorithm is applied, the constants should notbe stored; this algorithm is based on the search for the minimum value of the diagnostic functional amongthe values of this functional that were obtained in the process of diagnostics for the a priori chosen set ofreference malfunctions. Various extensions of the diagnostic theorem are considered, namely, the problem ofwhether the diagnostic algorithms thus obtained are applicable when the dimension of the diagnostic vectorbeing used is lower than that of the state vector or when the uninterrupted express-diagnostics with nochecking surface is carried out, the problem of selecting the minimum diagnostic time, the diagnostics ofmalfunctions occurring in the neighborhoods of reference non-degenerate malfunctions and not envisaged inthe a priori list. We consider other functionals solving the diagnostic problem. Finally, we state the extendeddiagnostic problem that is solved by using the proposed algorithms.

Abstract:

Testicular neoplasms cause diagnostic difficulties for clinical and laboratory diagnostics in young and middle-aged men. Seminoma refers to germ-cell tumors (GCTs) and is the most common cancer of this localization. But the timely and correct diagnostics by non-invasive technologies is still difficult. The clinical case clarifies the innovative techniques by Sperm. Sediment Cytology (SSC) as the non-invasive diagnostic approach resulting in excellent tumor cells detection. While a non-invasive conventional diagnostics and laboratory examination are of low diagnostic value this method can help oncologists and urologists for a confident judgment about the nature of the process and the timely choice of further treatment tactics.

Abstract. The CFMIP Diagnostic Codes Catalogue assembles cloud metrics, diagnostics and methodologies, together with programs to diagnose them from general circulation model (GCM) outputs written by various members of the CFMIP community. This aims to facilitate use of the diagnostics by the wider community studying climate and climate change. This paper describes the diagnostics and metrics which are currently in the catalogue, together with examples of their application to model evaluation studies and a summary of some of the insights these diagnostics have provided into the main shortcomings in current GCMs. Analysis of outputs from CFMIP and CMIP6 experiments will also be facilitated by the sharing of diagnostic codes via this catalogue.Any code which implements diagnostics relevant to analysing clouds – including cloud–circulation interactions and the contribution of clouds to estimates of climate sensitivity in models – and which is documented in peer-reviewed studies, can be included in the catalogue. We very much welcome additional contributions to further support community analysis of CMIP6 outputs.

Abstract:

ObjectivesTo explore factors that influence behaviour in the utilisation of diagnostics by caregivers of sick children. Utilisation is defined as a caregiver assisting a child to get diagnostic tests done and return for follow-up of results. Understanding these experiences may help inform the development of interventions and implementation strategies to improve the use of diagnostics, thereby target treatment and optimise antibiotic use.DesignA rapid ethnographic qualitative study using 3 months of unstructured observations, 1 month of structured observations of diagnostic utilisation and 43 semi-structured interviews. Transcripts were coded and analysed using inductive thematic analysis. Findings were explored from a behavioural perspective through the lens of the ‘Capability, Opportunity, Motivation and Behaviour’ (COM-B) model for understanding behaviour. The multiple methods of investigation applied allowed for triangulation and cross-validation of the findings.SettingThe paediatric outpatient department of a teaching hospital in rural, central India.ParticipantsCaregivers of sick children attending the paediatric outpatient department who were sent for one or more diagnostic test.ResultsThree key themes were identified that influenced caregivers’ behaviour. Caregivers trusted and understood the importance of diagnostics but their acceptance wavered depending on the severity of illness and preference to treat their child directly with medicines. Caregivers struggled to access diagnostics, describing delays in testing, receiving results and follow-up, further complicated by travel time, distance and competing priorities such as work. Diagnostics were relatively cheap compared with other healthcare facilities however, the cost of the test, travel expenses and wages lost for missing work, were barriers to getting the tests done and returning for follow-up.ConclusionsDiagnostics are generally accepted and their purpose understood, however, the organisation of diagnostic services, direct and indirect costs hinder caregivers from using diagnostics. Improvements in accessibility and affordability may increase caregiver motivation to use diagnostics and return for follow-up.

Abstract:

The article deals with the process of diagnostics of future preschool educators’ research skills development. The need to develop a system of diagnostics of future preschool educators’ research skills development is justified by the need to develop students ’ components of research competence specified in the Federal State Educational Standard of Higher Education (FSES HE). The system of activity of the modern teacher of preschool education involves not only implementation of education and training of children, but also organization and conduct of research activities with pupils, elementary preparation of preschoolers for implementation of the analyzed activities in the future which justifies the need for diagnostics of future personnel educators’ research skills development in the process of their professional training in high school. The success of analyzed skills of future teachers’ development cannot be determined without diagnostic operations to identify the level of specialists’ research competence development. Thus, the purpose of this study is to solve the problem of criteria and indicators; determination the levels of research skills and their characteristics development. The aim of the research is realized by applying methods of pedagogical diagnostics, analysis and generalization. Practical and theoretical novelty of the study is justified by the fact that in its course, methods of selection and compilation of diagnostic tools, principles of implemented diagnostic operations and pedagogical conditions for their implementation are determined and a universal algorithm of actions for the use of diagnostic tools is developed. It allows determining the objective level of diagnostics of future preschool educators’ research skills development in order to imperfect it by adjusting and improving the whole methodological system. The results of the study allowed justifying the effectiveness of the developed system of pedagogical diagnostics which allows using it in future in determining diagnostics of future preschool educators’ research skills development.

Abstract:

Problem. Diagnostics or troubleshooting is an integral part of the operation of automotive technology, and as automotive systems become more complex, the need for diagnostic skills increases, so diagnostic methods by the human senses should be considered an integral part of technical diagnostics at all stages of a vehicle life cycle. Methodology. Analytical methods are used to study the methods of diagnosing vehicles with the help of the intellectual abilities of the operator-diagnostician. Results. The paper shows that the intellectual abilities of the operator-diagnostician play an important role in diagnosing vehicles, the advantages and disadvantages of such diagnostics are presented. The list of basic knowledge necessary for the operator-diagnostician is described as well as the type of operational documentation which is necessary to improve the efficiency of intelligent diagnostics. Intelligent diagnostics of vehicles is divided into stages and shows the wide possibilities of diagnosing by the senses and knowledge of the diagnostician. It is shown that a highly qualified diagnostician can significantly reduce the complexity of diagnosis. With qualified training, experienced mechanics determine up to 70-90% of malfunctions and failures of vehicles and units using organoleptic methods and simple tests. Originality. The stages of intelligent diagnostics of vehicles are singled out and the wide possibilities of diagnosing by the human senses and knowledge of diagnostics at these stages are shown. Practical value. The results of this work are intended for wide use, for example, for drivers, maintenance services, developers of operational and technical documentation, developers involved in the improvement of technical diagnostic tools, machine learning, etc.

Abstract:

The purpose of the article is to determine the economic diagnostics and development of measures to ensure the competitiveness of the enterprise in the transport market in conditions of variability and uncertainty of the external economic environment. The stages and methods of competitive analysis are analyzed. The relevance of the diagnostics of the enterprise is substantiated. The features of the current state of diagnostic systems at domestic transport enterprises are also determined, including the following: use of simple analytical diagnostic methods; a limited number of indicators that are used by managers as indicators of the state of enterprise; retrospective and current direction of diagnostics; use of accounting and statistical accounting data as information sources; predominance of symptomatic type of diagnostics and the single use of etiological diagnostics; use of diagnostics mainly to prevent a crisis state; lack of a formalized methodology for the implementation of economic diagnostics, taking into account industry specifics. The solution of the main problems of the diagnostic system at enterprises in modern economic conditions is proposed, namely: formation of a system of criteria (indicators) that can characterize the object and adequately reflect its condition, taking into account factors of influence; development of a scale for measuring the values of indicators that allow minimizing the influence of the subjectivity factor in the course of diagnosing; development of a formalized methodology for diagnosing the state of enterprises, taking into account the specifics of their activities and developing a methodology for choosing the best option for measures that facilitate the improvement of the work of all components of the object of study.

Abstract:

Currently, clinical laboratory diagnostics of male infertility is an integral part of the diagnostic process in the field of reproductive medicine. This review provides information about novel and traditional immunological, cellular, biochemical and other markers of human semen, which are used in the complex laboratory diagnostics of male infertility. Unfortunately, at present, due to the lack of updated clinical guidelines for male and female infertility diagnostics, uninformative algorithms and incompatible assessment criteria are increasingly used. This situation leads to controversial discussions, where the diagnostic functions of laboratory tests and markers are questioned. That is why the constant search is needed for innovative diagnostic approaches aimed at in-depth study of the pathogenesis of male infertility and subfertility.

Abstract:

The presented paper scientifically discusses the progressive diagnostics of electrical drives in robots with sensor support. The AI (artificial intelligence) model proposed by the authors contains the technical conditions of fuzzy inference rule descriptions for the identification of a robot drive’s technical condition and a source for the description of linguistic variables. The parameter of drive diagnostics for a robotized workplace that is proposed here is original and composed of the sum of vibration acceleration amplitudes ranging from a frequency of 6.3 Hz to 1250 Hz of a one-third-octave filter. Models of systems for the diagnostics of mechatronic objects in the robotized workplace are developed based on examples of CNC (Computer Numerical Control) machine diagnostics and mechatronic modules based on the fuzzy inference system, concluding with a solved example of the multi-criteria optimization of diagnostic systems. Algorithms for CNC machine diagnostics are implemented and intended only for research into precisely determined procedures for monitoring the lifetime of the mentioned mechatronic systems. Sensors for measuring the diagnostic parameters of CNC machines according to precisely determined measuring chains, together with schemes of hardware diagnostics for mechatronic systems are proposed.

Abstract:

This paper contains structured information on photodynamic diagnostics. Photodynamic diagnostics is a young diagnostic modality used in the detection of pre-neoplastic and very early neoplastic lesions. A characteristic feature of the presented method is its completely non-invasive nature and thus the possibility of multiple repetitions at the same patient. This is very important in modern health care and in preventive measures. Aim of the paper: The article aims to present technical and diagnostic possibilities of a photodynamic method as one of the possible modalities of screening diagnostics in patients with ambiguous clinical picture of early neoplastic lesions.
