An Accurate Method to Quantify Breathing-induced Prostate Motion for Patients Implanted with Electromagnetic Transponders

Purpose To validate and apply a method for the quantification of breathing-induced prostate motion (BIPM) for patients treated with radiotherapy and implanted with electromagnetic transponders for prostate localization and tracking. Methods For the analysis of electromagnetic transponder signal, dedicated software was developed and validated with a programmable breathing simulator phantom. The software was then applied to 1,132 radiotherapy...
