Advanced Physics for Brachytherapy 2018

Conclusions • Brachy plan must be evaluated using point doses (in some cases), DVH parameters, dose distribution and global indexes. • Overdose volumes due to “target points” based optimization must be carefully evaluated (more convenient “basal points”). • Resulting under-over dose volumes must be evaluated looking in detail at the 3D dose distribution. • For small volumes whole OAR volume subrogates well to the wall . • Sampling and histogram bar with must be selected with high resolution. • EQD2 evaluation in cervix GYN needs an adequate implementation on TPSs future versions by manufacturers in order to improve efficiency .
