Problems solved by technology

[0003] In some tumor radiation therapy systems, the particle beam generating device and accelerator are fixed on the ground, and the treatment room is set near the accelerator. Therefore, it is necessary to steer the particle beam emitted by the accelerator and guide it into the treatment room. Specifically, deflection magnets and focusing The complex system of magnets that direct the particle beam from the particle accelerator to the target is bulky and expensive to manufacture
In addition, the distance between the treatment room and the accelerator is large, and the energy loss of the particle beam will occur during the transmission process, which may lead to a decrease in the control accuracy of the irradiation dose

Abstract

The invention relates to a particle beam therapy apparatus. The particle beam therapy device comprises a fixed supporting device, a synchrotron, a rotary supporting device, a beam transporting deviceand an irradiation head. The fixed supporting device comprises a base, and a driving rotating mechanism is arranged on the base; the synchrotron is used for accelerating the particle beam, and a deflection magnet is arranged in the synchrotron; the rotary supporting device is rotatably arranged on the fixed supporting device; the rotary supporting device has a rotary center line when doing rotarymotion; the beam transporting device is used for receiving and transporting the particle beams output by the synchrotron; the beam transporting device is provided with a deflection magnet, and a deflection magnet in the beam transporting device and the deflection magnet in the synchrotron are at least partially the same in structure or parameter; an irradiation head is connected to the tail end ofthe beam transporting device, and particle beams are emitted to target tissue from the irradiation head.

Description

technical field [0001] The present disclosure relates to the technical field of tumor radiation therapy, and in particular to a particle beam therapy device. Background technique [0002] Particle accelerators can be used in tumor radiation therapy, such as accelerating particle beams in heavy ion therapy or proton therapy. The accelerated particle beam needs to be guided to the target tissue of the patient, and it is often necessary to irradiate the target tissue from different directions to enhance the therapeutic effect or reduce the irradiation dose to the surrounding healthy tissue. [0003] In some tumor radiation therapy systems, the particle beam generating device and accelerator are fixed on the ground, and the treatment room is set near the accelerator. Therefore, it is necessary to steer the particle beam emitted by the accelerator and guide it into the treatment room. Specifically, deflection magnets and focusing The complex system of magnets that guide particle...
