摘要：
The goal of this work is to correctly and completely take into account the anatomical information in the treatment planning of prostate cancer for high dose rate brachytherapy, By using fast simulated annealing algorithm to govern an inverse planning optimization, a highly conformal dose coverage to the target volume is obtained while minimizing urinary and rectal morbidity, Preliminary results show that our fast simulated annealing algorithm tan obtain a highly conformal dose to the prostate while preserving urethra and rectum wall within 15 to 20 minutes of cpu time.
