The first medical application of radiation to the medicine was performed immediately after the discovery of X-ray at 1985. Since then many kinds of the accelerator based radiations such as electron, neutron, proton, negative pion and heavy ion beams have been used to cure tumors. The technological development of the accelerator is deeply reflected in the modalities of the radiation therapy. In pursuit of a principle"higher dose to the tumor and less to the normal tissue" the pioneering researches in the proton and heavy ion therapy that utilize a Bragg peak are performed using cyclotron and synchrotron for physics researches. In the course of these studies many projects of the dedicated medical accelerator facilities have been planned and some of them are already in operation or are under construction. In this manuscript accelerators in the early years are reviewed briefly and most part is devoted to ones that are commonly used and newly built.
