Simulation of dose distribution irradiation
Večeřa, Petr ; Hlaváč, Martin (referee) ; Kolářová, Jana (advisor)
This project deals with the issue of simulation of dose irradiation. This principle is used in a radiotherapeutic device known as a Leksell Gamma Knife for the treatment of intracranial tumours. With regard to the theoretical observations obtained by studying this device, the project suggests the use of analytical geometry for the creation of a mathematical model for calculation of the intensity in the rayed area. A demonstration program Leksell_xvecer08 has been created for this model in a MatLab software background, which enables the user to change various input arguments and simulate a picture of the dosage spread in the target scanned areas.

Radiotherapy planning
Běťák, Ondřej ; Janoušek, Oto (referee) ; Kolářová, Jana (advisor)
The thesis is dealing with usage of ionizing radiation in radiotherapeutical treatment and designs demonstrative function for modelling the final radiation field in Matlab. The fundamentals is based on Leksell gamma knife . Leksell gamma knife uses 201 sources a it’s purpose is to treat tumours in brain tissue. The sources are placed static. In demonstrative function are 8 sources instead of 201 and there is 2D exposuring. The sources are equalized in defined coordinates in matrix 100x100. In demonstrative function is possible to set the number of activated sources, it’s beam width in isocentre and indirectly the angle of rotation of sources.
