Brachytherapy planning with using radiotherapy simulator and C-ARM
POHANKOVÁ, Jana
On the oncology department of Jihlava hospital is used fo rthe purposes os determing the position of resources for planning brachytherapy intended radiotherapeutic simulator. C - arm is used more during surgery. I had the opportunity to compare the two devices in test using a phantom - brachytherapy dice with lead bullets in the exact geometry. The purpose of the test was to find documentation to justify why the use of face radiotherapeutic simulator for planning teletherapy. The work is divided into four chapters. The first chapter deals with the theoretical part. Here describes the types of brachytherapy procedures, briefly also features a simulator and C -arm. Furthermore, there is a simple way explained geometric distortion using the image intensifier as a receptor. The second chapter is devoted to the description technical parameters of both the devices, phantom measurement methodology and method of evaluation of the measurement results. The third chapter presents the results of measurements of the positions of the balls in the phantom and fixed deviation between the determined and declared position for two ways to obtain images in orthogonal projection. The last chapter is devoted to discussion.
