SIMULATION INTENSITY MODULATE RADIATION THERAPY BY USING PENELOPE

Abstract

In this paper we present a simulation of intensity modulate radiation therapy (IMRT) with PENELOPE. The simulation of IMRT involves two problems. The first one is the modulation with tomotherapy and the second is the modulation with the movement of the multileaf colimator. Obtained results are the distributions of absorbed dose on the target volume and the organs at risk (OARs). The results show that IMRT could give a desired distribution of dose, which is enough for the target to kill the cancer cells and prevent the over dose of OARs. This paper also shows how to use PENELOPE for studies of the distribution of absorbed dose in radiotherapy.
