<p><P>PROBLEM TO BE SOLVED: To produce irradiation beams suitable for high-precision particle beam therapy such as a spot scanning method or the like. <P>SOLUTION: The particle beam therapy system includes a synchrotron which accelerates beams of charged particles to a desired energy level and permits outgoing of the beams of charged particles exceeding the stability limit, an irradiation device which irradiates an object with the beams of charged particles, a beam transport system which conducts the beams of charged particles outgoing from the synchrotron to the irradiation device, and a control unit which works in such a way as to remove part of the beams of charged particles circling in the synchrotron and allow the rest of the circling beams of charged particles to outgo from the synchrotron to be transported to the irradiation device. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
