R&D status in various countries
Japan leads the world in the field of heavy ion radiotherapy

Japan has approximately 20 years of actual results of clinical research

From the late 1970s, the Lawrence Berkeley National Laboratory (LBL) in the US conducted pioneering research on heavy ion radiotherapy using a preexisting accelerator constructed for nuclear experiments (this research has now concluded). Subsequently, Japan's National Institute of Radiological Sciences (NIRS: now QST hospital) started full-scale clinical research with the world's first system dedicated to heavy ion radiotherapy. About 29,000 patients (as of end of 2019) have been treated over approximately 25 years. Heavy ion radiotherapy has grown to be a highly effective, minimally invasive therapy, which is gaining recognition around the world.

An advanced medical technology, successfully developed in Japan for the first time in the world

The world’s first heavy ion radiotherapy using carbon ions was initially begun at the National Institutes for Quantum and Radiological Science and Technology, National Institute of Radiological Sciences (NIRS), Japan.
Japan’s heavy ion radiotherapy facilities successfully treated more than about 29,000 patients in the period from 1994 until end of 2019.
Heavy ion radiotherapy is a form of radiotherapy attracting a high level of interest around the world, and many institutions are considering the introduction of this treatment. Currently, in addition to the Hospital of the National Institute of Radiological Sciences (QST hospital), heavy ion radiotherapy is under operation at Gunma University Heavy Ion Medical Center, Hyogo Ion Beam Medical Center, Kyushu International Heavy Ion Beam Therapy Center, Kanagawa Cancer Center, Osaka Heavy Ion Therapy Center in Japan ; Heidelberg University in Germany; Institute of Modern Physics in China; Foundation CNAO in Italy; and Med-Austron in Austria. Furthermore, several other facilities are under construction (Taipei Veterans General Hospital in Taiwan and Yonsei University in Koria are introducing Japanese equipments.) or being planned.
