Development of Treatment Planning System in Peking University

The research on 3D conformal radiotherapy with a pencil beam kernel dose model and some 3D visualization technologies were developed. The results have been coded to form a product HW-TPS which has been systematically evaluated in Hospitals. HW-TPS was further developed with an inverse optimized hybrid algorithm for IGRT. Our new effort on biology guided radiotherapy (BGRT) is on the way with a goal of integrating more functional imaging information to show the biological status of the tumor and its surrounding tissue.
