<P>PROBLEM TO BE SOLVED: To provide an inner gantry for use with a particle beam therapy system. <P>SOLUTION: A system includes a patient support and an outer gantry on which an accelerator is mounted to enable the accelerator to move through a range of positions around a patient on the patient support. The accelerator is configured to produce a proton or ion beam having an energy level sufficient to reach a target in the patient. An inner gantry includes an aperture for directing the proton or ion beam towards the target. <P>COPYRIGHT: (C)2013,JPO&INPIT |
