Abstract

The present work gives an illustration of Monte-Carlo simulations in the domain of imaging in radiotherapy. More precisely a MegaVolt Cone Beam Computed Tomography (MV-CBCT) system is modeled and simulated using the GATE Monte-Carlo platform. For this purpose a flat panel portal imaging from Perkin Elmer was simulated and added to a previously simulated Oncor linear accelerator from SIEMENS. The obtained model was validated qualitatively by simulating the real reconstruction of a patient image, and quantitatively by calculating and measuring the deposited dose.
