Dosimetric Evaluation of an Adaptive Planning Strategy for Implant Shift in HDR Prostate Brachytherapy

Abstract

The occurrence of significant implant shifts between CT simulation planning and first fraction delivery is a frequent challenge for HDR prostate brachytherapy treatment. Here, we present evidence supporting the viability of a first-order adaptation strategy as a viable alternative to the conventional practice of re-scanning and re-planning. Our findings underscore the potential of this approach to enhance workflow efficiency in HDR prostate brachytherapy.
