Nine (9) field IMRT, manually selected gantry positions which follow the shape of the target in the transverse view. The biggest challenge in this case proved to be the amount of prescription dose outside of the high dose target (volume of regret). This is probably the effect of 1cm leaves but the effect was minimized by rotating the collimator to unique angles per gantry position (as evidenced by the comparatively high plan score). Collimator rotation was selected after an evaluation of the beam’s eye view in an attempt to mimic the angle or shape of the target.
Prostate postoperatvie only case, fractionated. All constraints on the bladder, rectum, bowel are met. This is a clinically acceptable plan.
