Abstract:

Background Approximately 2% of patients in primary care practice and up to 25% of hospital patients are registered as being allergic to an antibiotic. However, up to 90% of these registrations are incorrect, leading to unnecessary prescription of 2nd choice antibiotics with the attendant loss of efficacy, increased toxicity and antibiotic resistance. To improve registration, a better understanding is needed of how incorrect labels are attributed. Objective To investigate the quality of antibiotic allergy registration in primary care and identify determinants to improve registration of antibiotic allergies. Design Registration of antibiotic allergies in primary care practices were analysed for 1) completeness and 2) correctness. To identify determinants for improvement, semi-structured interviews with healthcare providers from four healthcare domains were conducted. Participants A total of 300 antibiotic allergy registrations were analysed for completeness and correctness. Thirty-four healthcare providers were interviewed. Main measures A registration was defined as complete when it included a description of all symptoms, time to onset of symptoms and the duration of symptoms. It was defined as correct when the conclusion was concordant with the Salden criteria. Determinants of correct antibiotic allergy registrations were divided into facilitators or obstructers. Key results Rates of completeness and correctness of registrations were 0% and 29.3%, respectively. The main perceived barriers for correct antibiotic allergy registration were insufficient knowledge, lack of priority, limitations of registration features in electronic medical records (EMR), fear of medical liability and patients interpreting side-effects as allergies. Conclusions The quality of antibiotic allergy registrations can be improved. Potential interventions include raising awareness of the consequences of incomplete and the importance of correct registrations, by continued education, and above all simplifying registration in an EMR by adequate ICT support.

Abstract:

Purpose: Expert selected landmark points on clinical image pairs to provide a basis for rigid registration validation. Using combinatorial rigid registration optimization (CORRO) provide a statistically characterized reference data set for image registration of the pelvis by estimating optimal registration. Materials ad Methods: Landmarks for each CT/CBCT image pair for 58 cases were identified. From the landmark pairs, combination subsets of k-number of landmark pairs were generated without repeat, forming k-set for k=4, 8, and 12. A rigid registration between the image pairs was computed for each k-combination set (2,000-8,000,000). The mean and standard deviation of the registration were used as final registration for each image pair. Joint entropy was used to validate the output results. Results: An average of 154 (range: 91-212) landmark pairs were selected for each CT/CBCT image pair. The mean standard deviation of the registration output decreased as the k-size increased for all cases. In general, the joint entropy evaluated was found to be lower than results from commercially available software. Of all 58 cases 58.3% of the k=4, 15% of k=8 and 18.3% of k=12 resulted in the better registration using CORRO as compared to 8.3% from a commercial registration software. The minimum joint entropy was determined for one case and found to exist at the estimated registration mean in agreement with the CORRO algorithm. Conclusion: The results demonstrate that CORRO works even in the extreme case of the pelvic anatomy where the CBCT suffers from reduced quality due to increased noise levels. The estimated optimal registration using CORRO was found to be better than commercially available software for all k-sets tested. Additionally, the k-set of 4 resulted in overall best outcomes when compared to k=8 and 12, which is anticipated because k=8 and 12 are more likely to have combinations that affected the accuracy of the registration.

Abstract:

Objective: Navigation systems create a connection between imaging data and intraoperative situs, allowing the surgeon to consistently determine the location of instruments and patient anatomy during the surgical procedure. The best results regarding the target registration error (measurement uncertainty) are normally demonstrated using fiducials. This study aimed at investigating a new registration strategy for an electromagnetic navigation device. Methods: For evaluation of an electromagnetic navigation system and comparison of registration with screw markers and automatic registration, we are calculating the target registration error in the region of the paranasal sinuses/anterior and lateral skull base with the use of an electromagnetic navigation system and intraoperative digital volume tomography (cone-beam computed tomography). We carried out 10 registrations on a head model (total n = 150 measurements) and 10 registrations on 4 temporal bone specimens (total n = 160 measurements). Results: All in all, the automatic registration was easy to perform. For the models that were used, a significant difference between an automatic registration and the registration on fiducials was evident for just a limited number of screws. Furthermore, the observed differences varied in terms of the preferential registration procedure. Conclusion: The automatic registration strategy seems to be an alternative to the established methods in artificial and cadaver models of intraoperative scenarios. Using intraoperative imaging, there is an option to resort to this kind of registration as needed.

Abstract:

To improve lung tumor conspicuity during CT-guided cryoablations, we used nonrigid image registrations to fuse pre-procedural MR images and intra-procedural CT images and determined which set of CT images taken at planning, targeting, and monitoring phases of the procedure provided the most accurate and fastest registrations. In 10 percutaneous CT-guided cryoablation procedures, MR images were registered with intra-procedural CT images using a nonrigid registration technique using an intensity-based approach with affine and B-Spline transformations. The time to complete the registration as well as the accuracy of the registration defined by Target Registration Error (TRE), Dice Similarity Coefficient (DSC), and Hausdorff Distance (HD) were measured to assess the performance of the registration. The least significant difference (LSD) method was used as a post-hoc analysis for comparing time and accuracy among planning, targeting, and monitoring phases. The mean TRE of the registration ranged from 6.26 (planning) to 10.31 (monitoring) mm. The mean DSC ranged from 83.86 (monitoring) to 89.22 (planning). The mean HD values ranged from 7.74 (targeting) to 12.20 (monitoring). Mean registration time ranged from 68.67 (monitoring) to 92.02 (planning) s. Using HD, registrations in either the planning or targeting phase were more accurate than in the monitoring phase. The registration was faster using monitoring images than using planning images. Nonrigid registration techniques can be used to fuse pre-procedural MR images with intra-procedural CT images with varying performance depending on the CT images taken at the different phases of the procedure. Therefore, caution should be taken in setting expectations on accuracies and speeds of registration depending on the phases of the CT-guided ablation procedures.

Abstract:

This paper examines the determinants of the difference between soccer player registration transfer fees and the estimated inherent value of transferred players. The results show that this difference increases for players competing in the same league as that of the acquiring team, players acquired during winter transfer windows, defender registrations, and in the presence of player registration swaps. It decreases for midfielder registrations and for registrations purchased the year immediately before the expiration of players’ contracts. Finally, the difference between registration transfer fees and estimated players’ inherent value increases up to when players are 28 years old and decreases afterwards.

Abstract:

Abstract Objective. Mutual information (MI) is consolidated as a robust similarity metric often used for medical image registration. Although MI provides a robust registration, it usually fails when the transform needed to register an image is too large due to MI local minima traps. This paper proposes and evaluates Generalized MI (GMI), using Tsallis entropy, to improve affine registration. Approach. We assessed the GMI metric output space using separable affine transforms to seek a better gradient space. The range used was 150 mm for translations, 360° for rotations, [0.5, 2] for scaling, and [−1, 1] for skewness. The data were evaluated using 3D visualization of gradient and contour curves. A simulated gradient descent algorithm was also used to calculate the registration capability. The improvements detected were then tested through Monte Carlo simulation of actual registrations with brain T1 and T2 MRI from the HCP dataset. Main results. Results show significantly prolonged registration ranges, without local minima in the metric space, with a registration capability of 100% for translations, 88.2% for rotations, 100% for scaling and 100% for skewness. Tsallis entropy obtained 99.75% success in the Monte Carlo simulation of 2000 translation registrations with 1113 double randomized subjects T1 and T2 brain MRI against 56.5% success for the Shannon entropy. Significance. Tsallis entropy can improve brain MRI MI affine registration with long-range translation registration, lower-cost interpolation, and faster registrations through a better gradient space.

Abstract:

AbstractWhen the Land Registration Act 2002 first came into force, the prevailing academic view was that it had created a system of “title by registration”, such that, where someone (B) is mistakenly registered as owner of another person's (A's) land, he acquires a good title (notwithstanding the mistake) that can validly be conveyed to someone else (C). The thesis of this article is that, whilst the logic of the “title by registration” principle might be conceptually attractive, it has proven to be unworkable in practice, is questionable as a matter of policy, and – looking to the future – ought to be abandoned in favour of a more subtle legislative scheme for resolving A-B-C disputes.

Abstract:

Medical images registration technique is important to the modern clinical medicine. A registration algorithm of medical images is proposed in the paper. The algorithm consists of two part, i.e. the rough registration and the fine registration. In the rough registration procedure, the contour lines of the couple medical images are obtained at first, then they are resampled to obtain fewer contour feature points. The rough registration is accomplished based on the resampled contour lines and the Principal Axes method. In the fine registration procedure, the simplified multiwavelet transform is used to obtain the couple images multiscale information at first, then part of high-frequency coefficients are selected as registration objects. In addition, the selected high-frequency sub-bands are filtered by their mathematical expectation, and hierarchical registration strategy is used in the registration process. The experiment results show that the proposed registration algorithm is an effect method, not only the registrations precision can be held, but also the calculation cost is reduced.

Abstract:

Aims: To establish the prevalence of jaw registrations being taken for removable partial dentures (RPDs) in primary dental NHS practices. Method: 271 RPDs made by 16 general dental practitioners across four NHS dental practices were evaluated prospectively. The number of teeth replaced, whether jaw registration was undertaken, and the number of denture adjustment appointments were recorded. Telephone interviews with dental technicians were held to establish their preferred jaw registrations material. Main findings: Jaw registrations were not carried out in 27% (n=72) of RPD. When jaw registration was recorded, 14% (n=28) required a further denture adjustment appointment. 64% (n=46) of dentures where jaw registration was not recorded required at least one further denture adjustment appointment. Dental technicians unanimously preferred a squash-bite wax block, with centre and canine positions marked and cast models secured with elastic bands. Conclusion: Overall, recording a jaw registration reduced the number of denture adjustment appointments required.

Abstract:

Abstract Objective: For frameless stereotaxy, users can choose between anatomic landmarks (ALs) or surface fiducial markers (FMs) for their match points during registration to define an alignment of the head in the physical and radiographic image space. In this study, we sought to determine the concordance among a point-merged FM registration, a point-merged AL registration, and a combined point-merged anatomic/surface-merged (SM) registration, i.e., to determine the accuracy of registration techniques with and without FMs by examining the extent of agreement between the system-generated predicted value and physical measured values. Methods: We examined 30 volunteers treated with gamma knife surgery. The frameless stereotactic image-guidance system called the StealthStation (Medtronic Surgical Navigation Technologies, Louisville, CO) was used. Nine FMs were placed on the patient's head and four were placed on a Leksell frame rod-box, which acted as a rigid set to determine the difference in error. For each registration form, we recorded the generated measurement (GM) and the physical measurement (PM) to each of the four checkpoint FMs. Bland and Altman plot difference analyses were used to compare measurement techniques. Correlations and descriptive analyses were completed. Results: The mean of values for GMs were 1.14 mm for FM, 2.3 mm for AL, and 0.96 mm for SM registrations. The mean errors of the checkpoints were 3.49 mm for FM, 3.96 mm for AL, and 3.33 mm for SM registrations. The correlation between GMs and PMs indicated a linear relationship for all three methods. AL registration demonstrated the greatest mean difference, followed by FM registration; SM registration had the smallest difference between GMs and PMs. Differences in the anatomic registration methods, including SM registration, compared with FM registration were within a mean ± 1.96 (standard deviation) according to the Bland and Altman analysis. Conclusion: For our sample of 30 patients, all three registration methods provided comparable distances to the target tissue for surgical procedures. Users may safely choose anatomic registration as a less costly and more time-efficient registration method for frameless stereotaxy.

This paper presents a comprehensive literature review on point set registration. The state-of-the-art modeling methods and algorithms for point set registration are discussed and summarized. Special attention is paid to methods for pairwise registration and groupwise registration. Some of the most prominent representative methods are selected to conduct qualitative and quantitative experiments. From the experiments we have conducted on 2D and 3D data, CPD-GL pairwise registration algorithm and JRMPC groupwise registration algorithm seem to outperform their rivals both in accuracy and computational complexity. Furthermore, future research directions and avenues in the area are identified.

Abstract:

Traditional precedents and the prevailing view hold that regarding the usefulness of invalid registrations, if there is a third party with an interest in the registration before the agreement on its usefulness, the agreement is not effective in relation to that third party, and within that scope, the registration made useful is considered invalid as it does not correspond to the actual legal relationships. The decisions in question judged that in cases where a provisional registration, which is invalid, has been utilized to complete a final registration or a provisional transfer registration, (a) the utilization of the registration cannot be claimed against a third party with an interest in the registration, such as a provisional seizure creditor, but (b) among the parties to the agreement of utilization, the validity of the utilization agreement and the registration made useful can still be claimed. However, in the situations addressed by these decisions, the provisional seizure creditor, who is a third party with an interest in the registration, can only request the cancellation of such provisional registrations on behalf of the debtor (one of the parties to the utilization agreement) and therefore, cannot claim the invalidity of the utilization agreement and the registration made useful against the parties to the invalid registration utilization who cannot oppose them. However, the conclusion of (b) is incorrect, and therefore, the conclusions of the decisions in question cannot be considered correct. That is, the conclusion that in the presence of a third party with an interest in the registration, the agreement of utilization and the registration made useful are invalid only in relation to that third party, and the validity of the utilization agreement and the registration made useful can still be claimed among the parties to the utilization is not acceptable as it acknowledges the relative effect of real rights. When there is a third party with an interest in the registration, the utilization of an invalid registration should not be recognized. It is not that the validity of the agreement of utilization and the useful registration “cannot be claimed only against the third party with an interest in the registration” and “within that scope,” but rather, “in cases where there is a third party with an interest in the registration,” the agreement of utilization and the useful registration, not corresponding to the actual legal relationships, should be considered “invalid against everyone.” Here, “everyone” includes the parties to the agreement of utilization (the counterpart).

Abstract:

Image registration is a very fundamental and important part in many multi-sensor image based applications. Phase correlation-based image registration method is widely concerned for its small computation amount, strong anti-interference property. However, it can only solve the image registration problem with translational motion. Hence, we proposed a modified phase correlation registration method in the paper. We analyzed the principle of registration, gave the flow chart, and applied the method to the SAR image registration problems with scaling, rotation and translation transformation. Simulation results show that the method can accurately estimate the translation parameters, zoom scale and rotation angle of registrating image relative to the reference image.

Abstract:

Objective To evaluate the accuracy, reliability, and efficiency of voxel- and surface-based registrations for cone-beam computed tomography (CBCT) mandibular superimposition in adult orthodontic patients. Methods Pre- and post-orthodontic treatment CBCT scans of 27 adult patients were obtained. Voxel- and surface-based CBCT mandibular superimpositions were performed using the mandibular basal bone as a reference. The accuracy of the two methods was evaluated using the absolute mean distance measured. The time that was required to perform the measurements using these methods was also compared. Statistical differences were determined using paired t-tests, and inter-observer reliability was assessed by intraclass correlation coefficients (ICCs). Results The absolute mean distance on seven mandible surface areas between voxel- and surface-based registrations was similar but not significantly different. ICC values of the surface-based registration were 0.918 to 0.990, which were slightly lower than those of voxel-based registration that ranged from 0.984 to 0.996. The time required for voxel-based registration and surface-based registration was 44.6 ± 2.5 s and 252.3 ± 7.1 s, respectively. Conclusions Both methods are accurate and reliable and not significantly different from each other. However, voxel-based registration is more efficient than surface-based registration for CBCT mandibular superimposition.

Full text

Abstract:

Abstract In almost all projects, in which terrestrial laser scanning is used, the scans must be registered after the data acquisition. Despite more and more new and automated methods for registration, the classical target-based registration is still one of the standard procedures. The advantages are obvious: independence from the scan object, the geometric configuration can often be influenced and registration results are easy to interpret. When plane black-and-white targets are used, the algorithm for estimating the target center fits a plane through the scan of a target, anyway. This information about the plane orientation has remained unused so far. Hence, including this information in the registration does not require any additional effort in the scanning process. In this paper, we extend the target-based registration by the plane orientation. We describe the required methodology, analyze the benefits in terms of precision and reliability and discuss in which cases the extension is useful and brings a relevant advantage. Based on simulations and two case studies we find out that especially for registrations with bad geometric configurations the extension brings a big advantage. The extension enables registrations that are much more precise. These are also visible on the registered point clouds. Thus, only a methodological change in the target-based registration improves its results.

Abstract:

We study the performance of CLAIRE—a diffeomorphic multi-node, multi-GPU image-registration algorithm and software—in large-scale biomedical imaging applications with billions of voxels. At such resolutions, most existing software packages for diffeomorphic image registration are prohibitively expensive. As a result, practitioners first significantly downsample the original images and then register them using existing tools. Our main contribution is an extensive analysis of the impact of downsampling on registration performance. We study this impact by comparing full-resolution registrations obtained with CLAIRE to lower resolution registrations for synthetic and real-world imaging datasets. Our results suggest that registration at full resolution can yield a superior registration quality—but not always. For example, downsampling a synthetic image from 10243 to 2563 decreases the Dice coefficient from 92% to 79%. However, the differences are less pronounced for noisy or low contrast high resolution images. CLAIRE allows us not only to register images of clinically relevant size in a few seconds but also to register images at unprecedented resolution in reasonable time. The highest resolution considered are CLARITY images of size 2816×3016×1162. To the best of our knowledge, this is the first study on image registration quality at such resolutions.

Abstract:

A novel method combing feature constraint with multilevel strategy to improve simultaneously the registration accuracy and speed is proposed for non-parametric image registrations. To images between which the local difference is large, integrating feature constraint constructed with local structure information of images into objective function of image registration improves the registration accuracy. When applying feature constraint under multilevel strategy, parameter searching is prevented from entrapped into local extremum by using the optimization result on coarser levels as the starting points on finer levels; meanwhile traditional optimization methods without demanding intelligent optimization algorithms which consume more time can find the accurate registration parameter on finer levels, so registration speed is improved. Experimental results indicate that this method can finish fast and accurate registration for images between which there exists large local difference.

Abstract:

AbstractTrends in the civil registration of fetal death in multiple gestations that has occurred before, but expelled from the womb after, 24 weeks' gestation are examined using England and Wales 1993–2004 registration obtained from the Office for National Statistics. Count was made of fetal death registrations in which fetus papyraceous, fetal death before 24 weeks' gestation or fetocide before 24 weeks' gestation was recorded. There were 3700 fetal death registrations among 217,595 twin, triplet and higher order multiple births in England and Wales between 1993 and 2004. In 354 (9.6%) of these fetal deaths, death was recorded as having occurred before 24 weeks' gestation. There has been a threefold increase in such fetal death registrations. It is a legal requirement of parents to register a fetal death. The definition of a fetal death that meets formal registration criteria is that the fetus is expelled from the womb after 24 weeks' gestation. However, if the fetal death occurs before 24 weeks, there is confusion, nationally and internationally, whether or not registration is legally required. Fetal death in a multiple gestation has serious clinical implications for a surviving co-conceptus and failure to inform parents of an early death in a multiple gestation may have important repercussions. Legal definition for the registration of fetal death requires international agreement and application.

Abstract:

Inappropriate production, storage and use of chemical could cause chemical incident. Chemical registration will contribute to the safe management of chemical. Represented by U.S. TSCA (Toxic Substances Control Act) regulations and the European REACH (Registration, Evaluation and Authorization of Chemicals), the awareness of building chemical registrations or chemical database is raising. By carrying out extensive research and comparing the chemical registration regulation status of eight selected countries/regions, the study is to compare the current management status of chemical registration in different developed and developing countries, which may provide information and overview for preventing, controlling and reducing chemical incident, improving safe management of chemical, and supporting the development of chemical registration database.

Abstract:

Image stitching combines multiple overlapping scenes into a panorama. It can be applied in video stitching, super-resolution, and medical imaging. Post-processing routines such as exposure compensation, seam line adjustment, and blending are often performed to increase its visual appeal. Our aim is to increase the registration accuracy between adjacent image pairs in a stitching algorithm. This is done by adding an area-based registration step, namely Enhanced Correlation Coefficient (ECC), which refines the original feature-based image registration. The performance of registrations in the stitching algorithm is evaluated using root-mean-squared error of control points, structural similarity index, and universal image quality index. The Boat and Graffiti datasets from the Oxford Robotics Database are used for experiments. It is found that ECC largely improves registrations in stitching except for a slight increase in root-mean-squared error of control points in the Boat dataset. In addition, ECC’s enhancement makes the registration outperform the ground truth in one image of both datasets.

Abstract:

Background: The North Denmark Region implemented an electronic Prehospital Patient medical Record (PPR) in 2006. In 2015 a new version of the PPR was implemented. Implementation of new technologies can be challenging, including structurally and organizational obstacles, which causes difficulty in achieving data completeness. The aim was to examine completeness of registrations of vital parameters in PPR before and after the new version, and examine the distribution of the registrations. Method: The cohort includes all patients to whom an ambulance was dispatched after an emergency 112-call in the North Denmark Region from 2007-2014 and 2016. We examined the registration and distribution of six vital parameters, and included the first measurement. A trend analysis was used to assess the change in registration from 2007-2014, 2016. To exclude outliers in registrations we defined cut-points for systolic blood pressure (BP) (250mmHG), heart rate (HR) (250 beats per minute), and Respiratory Rate (RR) (100 breaths per minute), based on clinical relevance and their natural distributions. The other vital parameters had well-defined cut-points. We examined the distributions with and without outliers. Results: We identified 220,173 patients. Percentage of registrations without outliers from 2007 to 2014 vs. 2016: BP 73% to 86% vs. 81%, HR 76% to 88% vs. 81%, blood oxygenation (SpO2) 72% to 85% vs. 81%, RR 34% to 82% vs. 77%, Glasgow-Coma-Scale-score (GCS) 54% to 92% vs. 81%, Numeric Rating Scale for pain (NRS) 0% to 16% vs. 24%. Data from all years showed normal distributions for systolic BP and HR with mean (95% confidence interval): 141.8 (141.7; 142), 91.9 (91.8; 92.1), respectively. For RR, SpO2 and NRS; median (interquartile range) was: 18 (16; 20), 98 (95; 99), 6 (3; 8). From 2007-2014, 82% of the GCS-scores were on 15; in 2016 85% were on 15. There was 51% of the patients who had five vital parameters measured from 2007-2014 and 47% in 2016. Conclusion: Registration increased significantly from 2007 to 2014, with a significant decrease in 2016, except for the NRS-score. The decrease in 2016 is probably attributed the implementation process. Overall vital parameters were within normal ranges, despite outliers in registration.

Abstract:

Abstract Despite progress made towards increasing birth registration rates over the last dozen years, almost one in two children may still not get registered at birth in Niger according to a recent nationally representative household survey. What can be done to improve birth registration rates? This paper relies on a simple approach to measure how solving various obstacles to birth registration faced by parents could help increase birth registration rates. Controlling for other factors affecting birth registrations, the analysis relies on local-level reasons declared by households for not registering their children. The estimation method provides measures of potential gains in birth registration rates from different actions, including providing services closer to where households live, improving household knowledge about the fact that birth registration is both mandatory and beneficial for children, and reducing the out-of-pocket costs of birth registration. The analysis remains exploratory, but it provides hopefully useful insights about the likely benefits that could be derived from various policies utilized for increasing rates of birth registrations.
