摘要：
A particle therapy system includes a particle accelerator for generating a charged particle beam, a beam delivery device, a beam transport system for transporting the beam from the particle accelerator to the beam delivery device, and a supporting device for supporting a subject. The beam delivery device is rotatable around the target and with respect to the supporting device, so as to be able to deliver the beam to the target according to a plurality of irradiation angles. The system also includes a controller configured to make the beam delivery device rotate at a beam-on speed and meanwhile to irradiate the target with the beam. The controller is configured to make the beam delivery device rotate at at least two different beam-on speeds with respect to the supporting device, a first speed corresponding to a first irradiation angle and a second speed corresponding to a second irradiation angle.
