Prostate segmentation average results (±standard deviation) using the SRS algorithm with nonrigid registration for 15 patients contoured by 5 users, which includes DSC for the entire volume (%), volume ratio, MAD (mm), MAXD (mm), timesaving (%), and speedup factor. “i” in “Unedited i” represents the number of unedited slices in between any two slices that have been manually contoured
