According to statistics released by the International Particle Threading Collaborative Group (PTCOG), as of April 2017, there are more than 74 Particle Threading Facilities around the world (25 in the U.S. and 23 in Japan).
25 in the U.S. The U.S. currently has 25 proton therapy centers and many more are in the planning or construction phase.LLUMC was the first hospital-based proton radiotherapy center in the world. Massachusetts General Hospital was the first in the world to apply proton therapy to tumors in 1961.
Japan 23 Japan is currently the main market for proton therapy in Asia, and the number of ion centers is one of the highest in the world, and it has 1/3 of the world's proton centers, which are: 17 proton therapy centers, 5 heavy ion therapy centers, and 1 proton heavy ion center. HIMAC in Chiba Prefecture was the first heavy ion hospital in the world to be built and operated, and has accumulated a large number of heavy ion radiotherapy cases, and the Proton Center at Tsukuba University Hospital was opened in 1984.
There are still very few medical institutions in the world that have heavy-ion ray therapy facilities. Japan has five heavy-ion ray therapy facilities, and eighty percent of the world's heavy-ion ray therapy is performed in Japan.
China's three due to China's proton, heavy ion radiotherapy business started late, and even the need to purchase equipment from other countries, in 2015 only began to use proton treatment of tumors, the current domestic proton heavy ion institutions have been built in three, applied to the clinical treatment of only two, respectively, located in Shanghai, Zibo two places.
The cost in the United States is about 700,000 dollars or more, the cost in Japan is about a dozen to hundreds of thousands of RMB, and the domestic cost is about hundreds of thousands of dollars.
