Fig. 3From: Image-guided radiotherapy reduces the risk of under-dosing high-risk prostate cancer extra-capsular disease and improves biochemical controlDose fall-off in the posterolateral direction, averaged over all patients for all treatment plans. This is also averaged between the left and right regions for each patient. The 0 cm distance point is the average of the whole CTV. The probability of the existence of extra-capsular disease for the whole cohort of high-risk patients is plotted onto the secondary axisBack to article page
