Proton Beam Radiotherapy

Dr. Koji Tsuboi became very interested in proton beam radiotherapy (PBT) soon after the Proton Medical Research Center (PMRC) was established in the University of Tsukuba in 1983, and he participated in clinical research on PBT of brain tumors. As he wanted to deepen his understanding of particle beam radiobiology, he spent two and a half years at the Life Sciences Division of the Los Alamos National Laboratory in US as a visiting scientist. Based on research achievements in the US, he became involved in research on biological effects of carbon and proton beams at Japan's National Institute of Radiation Science and PMRC, and in 2006 he became a professor at PMRC. In the field of basic radio-biology, he has been conducting research on the targeted-effects such as DNA damage and cell death induced by various particle beams, as well as research on the non-targeted effects of activation of systemic anti-tumor immune response by proton beams. As for clinical studies, he has been involvedin high dose PBT for glioblastomas and skull base chordomas. He has many publications in both basic and clinical fields.

Dr. Takeji Sakae has continued research in the field of medical physics, which related to equipments for proton beam preparation and quality control. In this field, due to advancements such as scanning irradiation and target tracking, equipment and software have become more complicated year by year. In order for the system to obtain reliability and stability, it is considered important to have a balanced quality control that covers the entire system.
