  Based on brief analysis of accelerators widely used for proton-ion therapy and patient cure during last 20 years the feasibility and importance of compact superconducting synchrocyclotrons operating at magnetic field level up to 10 T is outlined. The main component of modern commercial facility for proton-ion therapy is an isochronous cyclotron with room temperature or superconducting coils accelerating protons up to 250 MeV as well as synchrotron accelerating carbon ions up to 400 MeV/A. Usually ions are delivered from accelerator into the treatment room by transport lines. Irradiation is done by system of pointed to the patient magnets, collimators, energy degraders which are attached to the rotating Gantry. To greatly reduce price of facility (almost in one order of magnitude) and to simplify operational conditions of hospital personal it is proposed to provide iso-centric rotation of compact superconducting synchrocyclotron around the patient. Main physical and technical parameters are described in the paper.
