Dose distributions in prostate brachytherapy: comparison between Sievert and Monte Carlo methods

摘要

In the present work we discuss two numerical methods for the calculation of 3D spatial dose distributions, and their application in HDR prostate brachytherapy. We include a comparison between the results obtained with the Sievert integral method and the use of tables generated by Monte Carlo simulations of radiation transport in a homogeneous medium for two types of 192{sup left}Ir encapsulated sources commonly used in Mexican hospitals. The application of both methods to clinical data is also presented.
