Three dimensional intensity modulated brachytherapy (IMBT): Dosimetry algorithm and inverse treatment planning

Abstract

In this study, a dosimetry method for IMBT sources was proposed and an inverse treatment planning system prototype for IMBT was developed. The improvement of plan quality by 3D IMBT was demonstrated using ten APBI case studies. Faster computers and higher output of the source can further reduce plan optimization and delivery time, respectively.
