Proton therapy complex with three procedure rooms

Since 1969 a number of Moscow medical centers has carried out proton radiation therapy of patients with different types of diseases by ITEP synchrotron proton beam with the energy up to 200 MeV. These irradiations employing a specially extracted proton beam are used in routine practice and are made in parallel with physical research program. Two additional channels as well as two new procedure rooms have been operated since 1982. A special ste-up of equipment, including clinical dosimetry devices, patient irradiation equipment (four special units) and computer-controlled systems are now installed at the facility. By present, more then 1500 patients have been irradiated. This report presents a description of physical and dosimetry equipment and techniques of irradiations. A summary table containing date about patients and clinical results is also presented. (author)
