manner. Mitsubishi Electric also provides staff training and commissioning
support to facilitate the early start up of treatment.

New Treatment Center

Okayama University / Tsuyama Chuo Hospital Proton Beam Cancer Center, is
located on the campus of Tsuyama Chuo Hospital (Shigeatsu Fujiki, Chairman),
and will be operated jointly with Okayama University (Kiyoshi Morita,
President). Tsuyama Chuo Hospital and Okayama University Medical School,
Department of Radiation Oncology (Susumu Kanazawa, Professor and Department
