Features of the facility

  • i-ROCK is Japan’s latest heavy ion radiotherapy facility, which started treatment in December 2015. This is the fifth heavy ion radiotherapy facility in Japan.
  • This is the world's first heavy ion radiotherapy facility established in a cancer center. Multimodal therapy for cancer treatment is anticipated, integrating surgical operations, radiotherapy, chemotherapy, and other methods.
