Modelling in pinnacle for distance extended source-patient and verification with film EBT2 technique

The objective of this work is modelled on the Pinnacle Scheduler the geometry used in our Center for the technique of Total body irradiation which consists of radiate to the patient, whose middle line is 366 cm from the source, in positions lateral decubitus, with 2 fields anteroposterior of 40 x 40 cm², rotated collimator 45 degree centigrade interposing a screen of methacrylate 1 cm thick to 29 cm ahead of the middle line.
