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

Abstract

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.
