Heavy particle radiation particles are entities (such as carbon carbon, helium element helium), and put a huge accelerator to the speed of light into the 6-8 accelerated speed, the depth of tumor cells directly, to wipe out cancer cells to achieve therapeutic effect, to put it simply, it such as "target radiation therapy."
The world's first experiment with heavy particle radiation to treat cancer institute is American Institute in 1970, using a neon-ion radiotherapy. Unfortunately, by that time only to basic research in physics with a large part of devices, to do clinical trials, it has not been good results, by 1993, on the shortage of funds as well as the old device ended.
Subsequently, thousands of leaves Japan Institute of Radiation Medicine (release medical research) is coupled with its experience to develop, and successfully developed for medical use heavy particle radiation device (Heavy Ion Medical Accelerator in Chiba, referred to as HIMAC), the main accelerator diameter of about 40 meters, 130 meters long week, Japan in June 1994 began to heavy particle radiation to treat cancer; after Germany's heavy particles Sciences Research Center, as well as Japan's Hyogo Prefecture Medical Center Li-particle radiation, but also began to heavy particle radiation to treat cancer.
