Real-Time Dosimetry for Prostate Brachytherapy Using TRUS and Fluoroscopy
A means of achieving real-time dosimetry for prostate brachytherapy using transrectal ultrasound (TRUS) and fluoroscopy has been developed. The approach is designed to fit into the current protocol used at the Vancouver Cancer Center (VCC) for prostate brachytherapy. The TRUS and fluoroscopic images are fused using a single fluoroscopic image of the TRUS probe. The tip of each needle, used to i...
متن کاملIn vivo real-time rectal wall dosimetry for prostate radiotherapy.
Rectal balloons are used in external beam prostate radiotherapy to provide reproducible anatomy and rectal dose reductions. This is an investigation into the combination of a MOSFET radiation detector with a rectal balloon for realtime in vivo rectal wall dosimetry. The MOSFET used in the study is a radiation detector that provides a water equivalent depth of measurement of 70 microm. Two MOSFE...
متن کاملPractical considerations for prostate HDR brachytherapy.
PURPOSE A process for prostate high-dose-rate (HDR) brachytherapy was developed and implemented successfully in the community hospital setting. The practical aspects of the program are reviewed and may serve as a foundation for clinics interested in offering this clinical service. METHODS AND MATERIALS A generic needle distribution geometry was established to accommodate target volumes of var...

متن کاملIs intraoperative real-time dosimetry in prostate seed brachytherapy predictive of biochemical outcome?
PURPOSE To analyze intraoperative (IO) dosimetry using transrectal ultrasound (TRUS), performed before and after prostate low-dose-rate brachytherapy (LDR-BT), and compare it to dosimetry performed 30 days following the LDR-BT implant (Day 30). MATERIAL AND METHODS A total of 236 patients underwent prostate LDR-BT using 125I that was performed with a three-dimensional TRUS-guided interactive ...
