SU‐E‐T‐537: Photon Beam Modeling and Verification of Collapsed Cone Convolution Algorithm for Dose Calculation in a Radiation Treatment Planning System

Purpose: The aim of this study is to evaluate the accuracy the collapsed cone convolution (CCC) algorithm for dose calculation in a radiation treatment planning system (TPS). Methods: We modeled various photon beams for various setup conditions in a radiation treatment planning system (CorePLANTM, Seoul CJ 20 cm2). Our next study will perform to compensate theses inconsistencies.
