Abstract of the Disclosure X-Ray and Electron Radiotherapy Clinical Treatment Machine A radiotherapy machine includes a microwavepowered accelerator 102 to produce an energetic beam100 of charged particles, bending and focussingmagnets 104, 108, 110, 112, 114 to scan the beam ina plane and collimators 120 to make the resultingscanned beam into parallel rays of charged particlesor x-rays. The beam is intensity modulated as it isscanned to control dosage. The subject is movedperpendicular to the scanning plane in order to treata 3-dimensional shape.
