The radio therapy process planning
Slavíček, Tomáš ; Kolářová, Jana (referee) ; Hrozek, Jan (advisor)
This thesis aims to bring reader to the problems of radiotherapy, to give him an overview of basic principles and methods used to treat patients with cancer by ionizing radiation. The first part is devoted to the physical description of radiation and means of quantification. Interactions of radiation with matter are discussed next following with characterization of radiation effects on living cells and tissues. In the next part there is a description of the devices used in the treatment by ionizing radiation and an explanation of the various acts of patient's preparation from the target localization to irradiation. The final chapter describes created program with a graphical environment, which includes the key elements of commercial planning systems for the creation of the irradiation plan. This program uses real CT images and provides the user a basic idea of creating radiotherapeutic plan. The user has several functions for creating and optimizing the plan. The output of the program is a graphical representation of the spatial distribution of dose in the patient's body.

Communication about radiation risks in medicine from the perspective of ethics
KAFKOVÁ, Monika
The diploma thesis deals with communication about radiation risks in medicine from the perspective of ethics. The aim of this work is to evaluate the quality of communication about radiation risks in medicine. Furthermore, it finds out what level of knowledge of ethical bases of communication radiology assistants and patients have. The work consists of a theoretical and a practical part. The theoretical part provides information about ionizing radiation, history of radiology, X-rays. Furthermore, the effects of radiation, principles and methods of radiation protection are described, as well as medical exposure, ethics in the radiation protection system and process ethical values. In the practical part, a survey was conducted focusing on communication about radiation risks in medicine from the point of view of ethics. Questionnaires were distributed to radiodiagnostic departments of selected hospitals. A sample of respondents consisted of 60 radiological assistants and 150 patients. The results of the questionnaire survey are processed into graphs. Based on the evaluation of all questionnaires, most patients are informed about radiation risks depending on the type of examination. Informed consent and verbal expression are among the most common ways of education about radiation risks. The results also show that a large proportion of respondents has not addressed any ethical issues in this context yet, and most radiology assistants have not even received any training in health ethics. Especially among patients, ignorance of some ethical concepts was an obstacle to completing certain questions in the questionnaire.
