A comparison of prostate IMRT and helical tomotherapy class solutions

The purpose of this study was to assess a variety of potential IMRT class solutions as compared to a helical tomotherapy (HT) class solution for localized prostate cancer. Target and critical structures were contoured on 10 prostate cancer patient CT datasets. HT treatment plans were compared to four different IMRT approaches by paired t-tests. HT prostate planning generally provided treatment plans with excellent target homogeneity and favorable critical structure sparing when compared to conventional IMRT.
