X-ray examination indicated at health center Strakonice depending on age
BRAUEROVÁ, Pavla
This thesis deals in theoretical part with X-rays, x-ray examinations of children and the elderly, radiation protection and medical exposure and requests for examination, the practical part drawn by x-ray examinations at the Health Center Strakonice Ltd. in the years 2010 - 2014 and conditions exhibited a request for examination in 2014. I set two aims, namely: Analyze the differences in X-ray indication among doctors depending on their expertise and age distribution of patients. Analyze the administrative formalities regarding the processing of requisitions for X-rays. To achieve the goals I have performed analysis and subsequent processing of data for the period of five years 2010 - 2014 concerning the age distribution of patients and formalites of requisitions for X-rays. I have processed statistical surveys created at the Health Center Strakonice Ltd. and the data from operational diaries and requisitions. The obtained data have been organized into graphs. There were defined two research questions: 1.Are practitioners for adults indicate substantial majority of RTG examination? 2. Are most common content gaps in the terms of the X-ray requisitions missing description of the disease and data on height and weight of the patient? At first research question can be answered in the negative and the other positive. In conclusion we can say that the X-rays still enjoys great popularity among imaging techniques due to its simplicity and accessibility. However, it is important to correctly indicate and ensure the right level of radiation protection, especially in pediatric patients.

The Radiochraphic techniques of Veterinary
PIVOŇKOVÁ, Klára
This Bachelor´s thesis deals with radiology imaging methods in veterinary medicine. Imaging modalities used in veterinary medicine include X-ray, ultrasound, computed tomography and magnetic resonance imaging. The previous four imaging devices are described in the thesis. As a matter of interest, the intraoral X-rays should also be a part of this summary. Radiation protection, which applies to the specialists who are mostly present in the X-ray examination and immobilize an animal, is crucial in veterinary medicine. Radiation protection of animals is not taken into account in this case. The purpose of this study is to form specific screening used for dog X-ray. This examination has a considerable diagnostic value and is relatively inexpensive. The thesis also describes advantages and disadvantages of X-ray and ultrasound, as well as analysing radiation protection in veterinary medicine. Since the radiation protection of animals is not taken into account, the study only focuses on the general principles of radiation protection to be observed by the staff. Advantages and disadvantages of X-ray and ultrasound are discussed in the theoretical part. A considerable advantage of these two devices consists in their availability since they are owned by a majority of veterinary clinics. The second part of the study evaluates the zoos having their own X-ray machine or ultrasound followed by the analysis of commercial offers of veterinary equipment. This analysis is based on the inquiry of prices for X-ray and ultrasound examination at individual clinics. The data were collected by using a questionnaire survey. The theoretical part of the Bachelor´s thesis describes the different imaging devices and summarizes the findings referring to protection against ionizing radiation. All sources used are included in the list of information sources. The practical part of this study primarily analyses research involving the participation of 9 zoos in the Czech Republic and 10 veterinary clinics in South Bohemian Region. The survey was conducted by using questionnaires. Some of them were completed by the staff, especially in the clinics in the České Budějovice. The remaining clinics and zoos provided information via e-mail. The questionnaire included clearly defined questions. The investigation was supposed to reveal the answer to research questions whether animal ultrasound is used more frequently compared to animal X ray and whether radiographers are involved in radiological imaging within veterinary medicine. Completed questionnaires provided the answer. Specific answers to the questions for each centre are included in the Chapter "Results". These centres are numbered because the questionnaires were anonymous. Majority of answers were processed in the charts. Survey results are assessed in the Chapter "Discussion". The answer to the research question "Is animal ultrasound used more frequently compared to animal X-ray?" is as follows: X-ray is used by 50% of respondents, ultrasound is used by 20% of respondents and 30% reported to frequently use both devices. The answer to the second research question - whether radiographers are involved in imaging methods in veterinary medicine - the answer was clear: they do not participate. Only one veterinary clinic stated to have this specialist but he only operates a computed tomography device. The study also reveals the number of X-ray equipment and computed tomography scanners in the Czech Republic, Prague Region, South Bohemian Region and České Budějovice. These results are demonstrated in the tables. The results of this thesis may bring new information to the professionals or can serve as tutorial or supplementary material for students.

Radiological Imaging of the Head
STEJSKALOVÁ, Pavla
The aim of the work is to inform students about comparison of special skull imaging methods and about computer tomography. According to the hypothesis the work was aimed at the petrous bone and its imaging. The survey was concentrated on the period from 2005 to 2008, whether the conventional special projections are being replaced in time and thanks to development of CT devices. The bachelor work also involves comparison of radiological standards individual hospitals adhere to.
