20.500.12556/RUL-105152 Primerjava sistemov za detekcijo sekundarnih žarkov gama pri protonski terapiji Comparison of secondary gamma rays detection systems for proton therapy V magistrskem delu sem obravnaval sisteme za detekcijo sekundarnih žarkov gama pri protonski terapiji. Obravnaval sem dva tipa detektorjev, kamero gama in Comptonsko kamero. Z Monte Carlo simulacijami sem simuliral tok protonov skozi fantom iz vode. Vzdolž poti so se vzbujala atomska jedra, ki so nato sevala sekundarne žarke gama, na katerih sem preizkušal različne implementacije kamere gama in Comptonske kamere. Uvedel sem enoten kriterij za primerjavo merilnih sistemov. Prišel sem do zaključka, da so slike troplasne Comptonske kamere in kamere gama primerljive kvalitete. Z obema kamerama dosežemo ločljivost slike 2 mm. In my master thesis, I studied systems for the detection of secondary gamma rays in proton therapy. I analyzed two types of detectors, a gamma camera and a Compton camera. I simulated the flow of the protons through a phantom made of water. Secondary gamma rays have been emitted. Those gamma rays have been used for testing and verification of various implementations of gamma ray detector. I compared and evaluated detection systems using common criteria. I came to the conclusion that three layer Compton camera has similar quality of the image as gamma camera. In both cases a resolution 2 mm can be achieved. protonska terapija simulacije Monte Carlo Comptonska kamera kamera gama Proton therapy Monte Carlo simulations Compton camera gamma camera true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2018-10-31 07:45:02 2018-10-31 07:45:06 2022-08-17 03:47:00 0000-00-00 00:00:00 2018 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 95217 3262052 413.pdf 413.pdf 1 C5FF2B2A4DE5670CF7CA127ACF9AE0FB 35b155c0e3fc5e99d0b5a2bca69223ba697608dc104939a522e276c9eb7af92c 20a1cadd-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=115756 Fakulteta za matematiko in fiziko 0 0 0
