From: Towards real-time PGS range monitoring in proton therapy of prostate cancer

Anterior-oblique plan for a 279\(^\circ \) gantry angle. (a) Photo of the prostate phantom lying on a rotating platform commanded remotely from the control room. The ERB was closer to detector 2. (b) Schematics of the irradiation of each IEL in a column-wise fashion. The Y-coordinates represent the horizontal direction and increase from left to right in the BEV, and the X-coordinates represent the vertical direction and increase from top to bottom. (c) Plans of the AO beam conforming to the prostate (d), and that overlapping with the ERB.
