Developing a Verification and Training Phantom for Gynecological Brachytherapy System
Introduction Dosimetric accuracy is a major issue in the quality assurance (QA) program for treatment planning systems (TPS). An important contribution to this process has been a proper dosimetry method to guarantee the accuracy of delivered dose to the tumor. In brachytherapy (BT) of gynecological (Gyn) cancer it is usual to insert a combination of tandem and ovoid applicators with a complicat...

متن کاملEvaluation of deformable image registration in HDR gynecological brachytherapy
Introduction: In brachytherapy, as in external radiotherapy, image-guidance plays an important role. For GYN treatments it is standard to acquire at least CT images and preferably MR images prior to each treatment and to calculate the dose of the day on each set of images. Then, the dose to the target and to the organs at risk (OAR) is calculated with worst case scenario from I...
متن کاملComparison of two planning systems for HDR brachytherapy gynecological application
PURPOSE This report compares the Nucletron NPS and PLATO planning system for patients treated for cervix cancer. MATERIALS AND METHODS This study compares calculations generated using the older NPS (version 11.43) planning system and the more recent PLATO (version 14.1) system for two cases: 1) a single dwell position and 2) an actual patient application using a tandem and ovoid. RESULTS Fo...
متن کاملComparison the treatment time of cobalt and iridium sources in HDR brachytherapy
Introduction: The use of long-half-life Cobalt source instead of iridium source will be very helpful in HDR brachytherapy for treatment of cervical cancer. The aim of this study was compared the treatment time with cobalt and iridium source in brachytherapy for treatment of cervical cancer using Tandem-ovoid applicator. Materials and Methods: In this study, 19...
