Abstract:
Study aimed at Monte Carlo (MC) modeling and dosimetric validation of GammaMed Plus 192Ir source for high dose rate brachytherapy using Geant4 code in TOPAS. Study investigated the several TG-43 guided dosimetric parameters for brachytherapy dose calculation. The excellent agreement was found between simulated and published data. The simulated MC dataset can be served as reference and fed into Treatment planning system (TPS) to verify brachytherapy dose calculation. Present MC modeling of brachytherapy source can be availed in further patient specific studies involving MC simulation.
