Tokai University, Department of Radiation Oncology, School of Medicine


The Tokai University Department of Radiation Oncology offers patients access to cutting-edge technologies for adult and pediatric tumors, including stereotactic radiosurgery (SRS), stereotactic body radiation therapy (SBRT), IMRT, and IGRT. Brachytherapy programs are also available for patients with gynecologic cancer.

Department clinicians attend 8 tumor boards, and discuss treatment strategy with clinicians of other departments.
State-of-the-art facility equipped with new Varian accelerators (2 Clinac21Ex, 1 TrueBeamSTx with Novalis system).

Number of patients treated was over 1000 patient a year.

IMRT, VMAT and SRT are increasing with TrueBeamSTx

VMAT: brain, head and neck, esophagus, prostate
SRT, SRS : brain, lung
