The equipment has five or other odd number of photon beams sources mounted on rotating frames guided by 4-D radioscanography and used for multi-beam orthovoltage isotropic cyclotherapy. These beams are used in combination with six sources of photon beams (8,9,10,11,12,13) mounted on fixed frames (15,16;17,18;19,20) which may however be rocked laterally.
