Abstract:
Introducing a Quality Assurance methodology appears particularly useful in Radiation Oncology due to the complexity of the procedures involved and the heterogeneity of the standards adopted, if any, in the great majority of the Centers. There are two possible ways of evaluating quality in the Health Environment: a formal, Institutional certification, or a voluntary one obtained through a mechanism of peer review. The European Society for Therapeutic Radiology and Oncology (ESTRO) started in 1994 with the publication of a methodological Report intended to be adopted by the individual national Societies, and this paper is an invitation to do it.

Abstract:
The radiotherapy clinics in Sweden have been without a functioning national platform consisting of dose data from patients undergoing radiotherapy. A national collaboration between clinics will improve the quality of radiotherapy since clinics will be able to compare dose data from treatment plans between clinics. It will also help and improve future researches in radiotherapy. A new national quality registry for radiotherapy in Sweden is under development and is located on the INCA platform. The aim of this study is to do a quality assurance of the INCA registry. The data stored in the registry are calculated from the treatment plans stored locally at the clinics. The quality assurance of the registry is done by creating a program run by Python code and by using Streamlit as the graphical user interface. The program takes dose and volume data from the dose volume histograms located in treatment plans from the INCA database and compares it with the dose and volume data from the local clinics' treatment planning system. The different treatment planning systems considered in the program are Oncentra(Elekta, Sweden), Eclipse(Varian, U.S.), RayStation(RaySearch Laboratories, Sweden) and Monaco(Electa, Sweden). The compared absorbed doses are the dose to 99% of the structure volume(D99%), D98%, D50%, D2% and D1%. The program generates how much the INCA data differs from the TPS data in percent and is named QARS(Quality Assurance of the Radiotherapy Database in Sweden). A verification of the created program and a preliminary evaluation is done on a limited dataset containing three patient groups(prostate patients, lung patients and head and neck patients) with five patients in each group. The dataset is run through the program with patient data from both Oncentra and Eclipse. The result indicates that all the near-maximum doses, D2% and D1% in INCA are very close to their corresponding TPS dose. There is a more noticeable difference in the near-minimum doses, D99% and D98% but also for some D50% where the difference seems to increase in larger structure volumes with very low doses and in very small structure volumes, smaller than 0.01 cm3. It is compared how well INCA agrees with Oncentra and Eclipse respectively and it is clear that Eclipse has a smaller difference to INCA than Oncentra for structures with very small volumes and larger structures with low doses. To summarise the study, it generates a program for quality assurance of the national quality registry for radiotherapy in Sweden which hopefully can help improve the quality of radiotherapy and help future researches in the field.

Abstract:
The work presented in this thesis was a step forward in applying statistics to the important problem of monitoring machine performance and quantifying optimal treatment quality assurance in radiotherapy. This research investigated the use of an analytical decision making tool known as Statistical Process Control (SPC) that employs statistical means to measure, monitor and identify random and systematic errors in a process based on observed behaviour. In this research, several treatment machine and planning system parameters were investigated and a method of calculating SPC based tolerances to achieve optimal treatment goals was highlighted in this study.

Abstract:
Magnetic resonance imaging (MRI) utilizes the magnetic properties of tissues to generate image-forming signals. MRI has exquisite soft-tissue contrast and since tumors are mainly soft-tissues, it offers improved delineation of the target volume and nearby organs at risk. The proposed Magnetic Resonance-only Radiotherapy (MR-only RT) work flow allows for the use of MRI as the sole imaging modality in the radiotherapy (RT) treatment planning of cancer. There are, however, issues with geometric distortions inherent with MR image acquisition processes. These distortions result from imperfections in the main magnetic field, nonlinear gradients, as well as field disturbances introduced by the imaged object. In this thesis, we quantified the effect of system related and patient-induced susceptibility geometric distortions on dose distributions for prostate as well as head and neck cancers. Methods to mitigate these distortions were also studied. In Study I, mean worst system related residual distortions of 3.19, 2.52 and 2.08 mm at bandwidths (BW) of 122, 244 and 488 Hz/pixel up to a radial distance of 25 cm from a 3T PET/MR scanner was measured with a large field of view (FoV) phantom. Subsequently, we estimated maximum shifts of 5.8, 2.9 and 1.5 mm due to patient-induced susceptibility distortions. VMAT-optimized treatment plans initially performed on distorted CT (dCT) images and recalculated on real CT datasets resulted in a dose difference of less than 0.5%.  The magnetic susceptibility differences at tissue-metallic,-air and -bone interfaces result in local B0 magnetic field inhomogeneities. The distortion shifts caused by these field inhomogeneities can be reduced by shimming.  Study II aimed to investigate the use of shimming to improve the homogeneity of local  B0 magnetic field which will be beneficial for radiotherapy applications. A shimming simulation based on spherical harmonics modeling was developed. The spinal cord, an organ at risk is surrounded by bone and in close proximity to the lungs may have high susceptibility differences. In this region, mean pixel shifts caused by local B0 field inhomogeneities were reduced from 3.47±1.22 mm to 1.35±0.44 mm and 0.99±0.30 mm using first and second order shimming respectively. This was for a bandwidth of 122 Hz/pixel and an in-plane voxel size of 1×1 mm2.  Also examined in Study II as in Study I was the dosimetric effect of geometric distortions on 21 Head and Neck cancer treatment plans. The dose difference in D50 at the PTV between distorted CT and real CT plans was less than 1.0%. In conclusion, the effect of MR geometric distortions on dose plans was small. Generally, we found patient-induced susceptibility distortions were larger compared with residual system distortions at all delineated structures except the external contour. This information will be relevant when setting margins for treatment volumes and organs at risk.   The current practice of characterizing MR geometric distortions utilizing spatial accuracy phantoms alone may not be enough for an MR-only radiotherapy workflow. Therefore, measures to mitigate patient-induced susceptibility effects in clinical practice such as patient-specific correction algorithms are needed to complement existing distortion reduction methods such as high acquisition bandwidth and shimming.

Abstract:
The expectation for continual improvements in the treatment of cancer has brought quality assurance in radiotherapy under scrutiny in recent years. After a cancer diagnosis a custom treatment plan is devised to meet the particular needs of the patient's condition based on their prognosis. A cancer treatment plan will typically comprise of several cancer treatment technologies combining to form a comprehensive programme to fight the malignant growth. Inherent in each cancer treatment technology is a percentage error in treatment accuracy. Quality assurance is the medical practice to minimise the percentage error in treatment accuracy. Radiotherapy is one of the several cancer treatment technologies a patient might receive as part of their treatment plan, and in-vivo dosimetry is a quality assurance technology specifically designed to minimise the percentage error in the treatment accuracy of radiotherapy. This thesis outlines the work completed in the design of a next generation dosimeter for in-vivo dosimetry. The proposed dosimeter is intended to modernise the process of measuring the absorbed dose of ionising radiation received by the target volume during a radiotherapy session. To accomplish this goal the new dosimeter will amalgamate specialist technologies from the field of particle physics and reapply them to the field of medical physics. This thesis describes the design of a new implantable in-vivo dosimeter, a dosimeter comprising of several individual stages of electronics working together to modernise quality assurance in radiotherapy. Presented within this thesis are the results demonstrating the performance of two critical stages for this new dosimeter, including: the oating gate metal oxide field effective transistor, a radiation sensitive electronic component measuring an absorbed dose of radiation; and the micro antenna, a highly specialist wireless communications device working to transmit a high frequency radio signal. This was a collaborative project between Rutherford Appleton Laboratory and Brunel University. The presented work in this thesis was completed between March 2007 and January 2011.

Abstract:
Quality assurance in radiation oncology is a set of processes and procedures designed to confirm that radiation therapy will be or has been administered appropriately, in a safe and well-documented manner. Adherence to these processes and procedures will ensure that accurate doses are delivered for planned exposures. To improve safety and prevent accidental exposures, it is advisable to introduce into the daily work of all personnel involved in the radiation therapy process, a system for tracking and recording any inconsistencies with the planned radiation therapy process. Identifying and tracking incidents increases safety and improves the quality of care.

Abstract:
An important element of a modern high-tech radiotherapy complex based on a linear electron accelerator is an electronic detector of portal images. It ensures the accuracy of the patient’s positioning on the treatment table, the compliance of the delivered dose distribution with the planned one, and allows for fast and accurate verification of treatment plans with volumetric modulation of the radiation intensity. The main provisions of the quality control of the electronic portal image detector are considered. It is shown that it includes the following stages: installation and commissioning of equipment; radiation dose control; calibration; quality control of clinical images; software testing; development of a quality assurance program that ensures the effectiveness and reliability of the patient’s radiation conditions in the course of radiation therapy.

Abstract:
To test the effectiveness of the dose delivery system of the treatment plan in intensity modulated radiation therapy, quality assurance systems are used. The main tool for verifying the correspondence between the reference and the estimated dose distribution is Y—indexing. In the process of Y—analysis of individual dose distributions, both point dose values and geometrical offset between the reference and delivered distributions are evaluated. To check the compliance of dose distributions, the concepts of action limits and tolerances are used. The action limits are defined as the total percentage of the estimated value by which deviation of the indicators checked by the quality assurance system is allowed, with a minimal risk of harm to the patient. Tolerances are defined as the boundaries of the magnitude change within which the treatment process is considered to be performed according to the prescribed conditions.

Abstract:
Radiation therapy of malignant neoplasms can cause radiation reactions and complications from normal tissues in patients. The main requirement for radiation protection of patients is the maximum possible dose reduction in normal organs and tissues surrounding the target. Another requirement for the provision of high-quality medical services is the establishment of a quality assurance system for radiation therapy in clinics. The article provides an overview of modern matrix detectors of ionizing radiation used in radiation therapy. The principle of operation of matrix detectors, which have been widely used on modern medical linear electron accelerators, is considered. It is shown that an important stage of the radiation therapy quality control program is the use of matrix detectors to assess the dose distribution in the patient’s body, the patient’s position on the treatment table and when evaluating the dosimetric parameters of the radiotherapy apparatus.
