Simulation of an ARM Processor for the Education of Programming in Assembler
Ondryáš, Ondřej ; Goldmann, Tomáš (referee) ; Orság, Filip (advisor)
This thesis aims to implement a didactic tool for simulation of an Arm-based processor integrated into the Visual Studio Code editor. The tool facilitates learning about the machine-level programming of these processors. It implements a service that provides an assembler and a simulator for the A32 instruction set. The service is built using the Unicorn emulation framework and other open-source tools. The editor extension uses the service to add support for the development and debugging of programs written in the assembly language. It shows descriptions of used instructions and helps the programmer understand their function. When debugging, it enables stepping through the code and provides various views of the state of the simulated processor, its registers and memory. The solution can be used in the Advanced Assembly Languages course at FIT BUT. It could be further improved in the future to support other architectures and provide an easy learning environment in other courses related to machine-level programming.

Dosimetric determination of radiation exposure of patients and personnel during diagnostic and interventional endovascular procedures at the DSA department of UVN, recovery plan for a potential extraordinary event
KRAHULA, Ondřej
Intervention radiology is a discipline that is achieving a great advancement due to its significant success in the treatment of various diseases. Also, it relates to the increase of the number of angiographic performances in the last years. The extension of radiological methods has increased the share of this discipline on the overall medical irradiation of the population. All angiographic performances are accompanied by certain risk related to the exposure of the patient and staff to the ionizing radiation. Several cases were reported where the surface doses were reaching the limits of deterministic effects of radiation in some types of examination. This study monitors three core criteria related to the radiation burden in the set of 141 patients, which have undertaken different endovascular interventions. These criteria are: the dose area product (DAP), surface dose, and effective dosage. The relevant criterion was the value of DAP, read from the DAP meter directly during the examination. Other data were calculated. On basis of these results, this study tries to determine the strenuousness of singular examinations from the point of the radiation burden. It is the understanding the principles of the influencing the patient{\crq}s burden of the radiation in angiographic examinations, what can help in reducing the dosages. The analysis of this study results can help to prevent the occurrence of abnormal events during the examination.

Methods of checking the observance of diagnostic reference levels in the field of radiodiagnostics
KROUPOVÁ, Helena
Methods of Checking the Observance of Diagnostic Reference Levels in the Field of Radio diagnostics Although there is a simultaneous development of diagnostic and therapeutic methods, perfection of instrumentation and means for personnel and patient protection, there is also an effort to reduce applied doses. In this way, medical irradiation caused by ionizing radiation used in medicine represents a significant contribution to the total dose of ionizing radiation that a person is exposed. Today the medical radiation in the Czech Republic comprises more than ninety per cent of radiation from an artificial source and approximately one ninth from the total population radiation. Evaluation of professional doctor radiation and X-ray devices attendance has been safeguarded within the personal dosimetry for many decades. However, systematic monitoring of doses related to medical radiation of the patient is a relatively new problem in the radiodiagnostics sphere. According to the Council directive 97/43/EUROATOM requirement, the SUJB has stated the so called ``diagnostic reference levels{\crqq} within enclosure number 9, Regulation No. 307/2002 Coll., about radiation protection. These ``diagnostic reference levels{\crqq} are dose levels within medical radiation and their exceeding is not expected at the 70 kg adult patient medical examination in the case of correct practice. The systematic exceeding of diagnostic reference levels under clinical practice conditions is the reason for reconsideration of radiation protection optimalization at a given workplace. In accordance with the proposal of the National Radiology Standards for Radiology Physics, the author team recommends the monitoring extension of the patient radiating load related to a particular medical radiation by specifying the local diagnostic reference levels, typical for a given type of workplace at a particular keeper, and their continuous verification within the clinical examination of the standard group of patients. Generally, the doses can be determined in two ways: by exposure parameter calculation or by product measure of area kerma, which is generally implemented by special devices, so called DAP meters. The aim of the work is the description of both methods, their comparison and the evaluation of the method effectiveness at various types of sciagrammatic workplaces.
