Three-comparatment complex for proton beam therapy

Since 1969 proton beam therapy of patients with different types of diseases using the ITEP synchrotron proton beam with the energy up to 200 MeV has been conducted in a number of Moscow medical centers. These irradiations employing a specially formed beam are used on a routine basis and are performed in parallel with the program of physical research. Two additional channels as well as two new procedure rooms have been in operation since 1982. A special setup of equipment including clinical dosimetry devices, equipment for patients' irradiation (4 special units), and computer-controlled systems have been installed at the facility. By the present time over 1300 patients have been irradiated. The authors describe physical and dosimetric equipment and irradiation techniques. A summary table containing data on the patients is provided
