Dose intercomparisons between computer planning, in-vivo and phantom measurements for Iridium-192 HDR Brachytherapy
During gynaecological high-dose rate (HDR) intracavitary brachytherapy (ICBT), invivo dosimetry is done to monitor the dose received by the bladder and rectum. This study was aimed at validating the need to do in-vivo dosimetry during ICBT. Thirty patients were recruited to participate in the …
