摘要：

The purpose of this study is to evaluate anatomy based inverse planning as implemented in PLATO BPS 14.2 for planning of HDR prostate implants. Six patients were analysed. The dose distributions were optimized using geometric optimization followed by graphical optimization (GO), anatomy based inverse planning or standard inverse optimization (SIO), tuned inverse optimization (TIO) and tuned inverse optimization followed by graphical optimization (GOTIO). The mean target coverage was 93 +/- 4%, 53 +/- 11%, 74 +/- 8%, 90 +/- 3%, respectively, for GO, SIO, TIO and GOTIO. The conformal index COIN was 0.74 +/- 0.02, 0.43 +/- 0.15 and 0.77 +/- 0.07, respectively, for GO, SIO and GOTIO. Improved dose homogeneity was found when comparing GOTIO with GO.
