Development of the accelerator-based technique for hadron therapy

Hadron therapy with protons and carbon ions is one of the most effective branches in radiation oncology. It has advantages over therapy using gamma-radiation and electron beams. Fifty thousands of patients per year need such a treatment in Russia. Review of the main modern trends in the development of accelerators for therapy and treatment techniques concerned with respiratory gated irradiation and scanning with the intensity modulated pencil beams is given. Main stages of forming, time-structure and main parameters of the beams used in proton therapy as well as requirements to medicine accelerators are considered. Main results of testing with the beam of C235-V3 cyclotron for the first Russian specialized hospital proton therapy center in Dimitrovgrad are presented. Using of the superconducting accelerators and gantry systems for hadron therapy is considered
