Top window (perspective) view of the confomal beam (transparent yellow), showing prostate tumor volume (cyan), bladder (violet), one femur head (white points), and patient external (transparent white).

Bottom left (Beam's Eye View) now clearly shows the accurate beam field contour, auto-generated to fit the tumor with a 1.5 cm margin, and a multi-leaf collimator auto-fitted to this contour (now only leaf outlines are shown in green).

Bottom right (Room's Eye View) shows orientation of the treatment machine gantry, collimator, and couch with patient structures including external.
