Movable horizontal intraoperative radiotherapy apparatus

Abstract

A movable horizontal intraoperative radiation therapy apparatus comprises a modulator, an electronic gun, an accelerating tube, a cooling system, a microwave system and a deflector, wherein the accelerating tube is arranged on a swing rack, the swing rack is connected with a support through a rotating shaft, the support is arranged on a cart, the rotating shaft of the rack is parallel to the shaft axis of the accelerating tube, the deflector is arranged a beam outlet which is positioned at the front end of the accelerating tube, the electronic gun is arranged at the rear end of the accelerating tube, the microwave system is arranged at the outer part of the accelerating tube and is connected with the swing rack, the modulator can be arranged outside an operation room and is connected through cables, a protection positioning sleeve is coaxially arranged with a beam line and is below the deflector, and the accelerating tube adopts an S waveband edge coupling standing wave or travelling wave accelerating tube. According to the radiation therapy apparatus, part of the weight of the accelerating tube is distributed at the rear end, and electrons are beamed out according to the required angle through the deflector, so the energy spectrum deflection is better than a direct-injection type; and the whole structure is more reasonable in load, and the radiation therapy apparatus can be carried into the operation room for intraoperative radiotherapy.

Description

Technical field: [0001] The invention relates to the field of nuclear physics, in particular to an electron linear accelerator, in particular to a high-energy electron linear accelerator used for radiation therapy in clinical medicine, and in particular to a movable horizontal intraoperative radiation therapy machine. Background technique: [0002] The therapeutic effect of ionizing radiation is the result of a series of physical, chemical and biological reactions after ionizing radiation acts on the human body. After resection of malignant tumor tissue during surgery, the exposed tissue has a good blood supply and is in a state of aerobic metabolism, so it is more sensitive to radiotherapy (oxygen effect). For non-eradication tumors, suspected non-eradication tumors or tumors that cannot be removed by surgery, a one-time high-dose irradiation of the tumor and residual lesions, as well as possible metastasis and recurrence sites, can play a role in the treatment of unresecta...
