| Abstract: | This paper reports on the development of an interactive, intraoperative dose planning system for seed implant brachytherapy in cancer treatment This system involves in-vivo dosimetry and the ability to determine implanted seed positions. The first stage of this project is the development of a urethral alarm probe to measure the dose along the urethra during a prostate brachytherapy treatment procedure. Ultimately the system will be used to advise the physicians upon reaching a preset dose rate or dose after total seed decay in urethra during the seed placement. The second stage is the development of a method and instrumentation for in-vivo measurements of the location of implanted seeds in the same frame as for dose planning, and using these in intraoperative treatment planning. We have developed a silicon mini-detector and preamplifier/amplifier system to satisfy the spectroscopic requirements of the urethral probe. This technique will avoid complications related to overdosing the urethra and the rectum. |
