The National Cancer Research Center The Eastern Cancer Research Center is the first medical institution to launch clinical applications in Asia. The clinical experience of abundant proton therapy is one of the highest in the world and has achieved the world's most advanced achievements in clinical medicine as well as medical physics and proton therapy technology.

  There are currently 35 research institutes specializing in particle therapy in Japan, of which 8 can be treated as proton. This hospital is the only hospital in Japan that uses cyclotron to treat high intensity continuous proton rays. Cyclotron irradiation of tumor tissue can be accomplished by a quantum ray in a short time, to reduce the patient's burden, so that the quantum beam can be positioned more accurately in the tumor tissue, because less physical activity during the patient's investigation is the shorter irradiation time . It also has a rotating bridge device that can irradiate the proton beam at an optimal angle to the tumor anywhere in the patient's body. In addition, we have successfully developed a system that enables real-time observation of a patient's proton irradiation area in the world.
