Neutron capture therapy system

Abstract

The invention provides a neutron capture therapy system. The invention aims to achieve reduction of neutrons which overflow from an irradiation chamber into an accelerator chamber. The neutron capturetreatment system comprises an accelerator, a beam shaping body, a charged particle transmission part and a shield body, wherein the accelerator is arranged in the accelerator chamber, and is used forgenerating charged particle beams, the beam shaping body is arranged in the irradiation chamber, and an accommodating part is arranged on the shielding wall of the accelerator chamber; an embedding part for embedding at least a part of the beam shaping body is arranged on the shielding wall of the irradiation chamber, neutron beams for treatment is generated through interaction of a neutron generation part in the beam shaping body with the charged particle beam, and the charged particle beam transmission part is used for transmitting the charged particle beams which are formed by the accelerator to the beam shaping body; and the charged particle beam transmission part is connected to the accelerator through the accommodating part, the charged particle beam transmission part is connected to the beam shaping body through the embedding part, and is used for transmitting the charged particle beams to the neutron generation part, and the shield body is located between the accelerator chamber and the irradiation chamber so as to reduce neutrons which are generated through interaction of the charged particle beams with the neutron generation part from entering the accelerator chamber through the accommodating part after the neutrons overflow from the embedding part.

Description

technical field [0001] The invention relates to a radioactive ray irradiation system, in particular to a neutron capture therapy system. Background technique [0002] With the development of atomic science, radiation therapy such as cobalt 60, linear accelerator, and electron beam has become one of the main means of cancer treatment. However, traditional photon or electron therapy is limited by the physical conditions of the radiation itself. While killing tumor cells, it will also cause damage to a large number of normal tissues along the beam path; in addition, due to the different sensitivity of tumor cells to radiation, traditional radiation therapy Treatment for more radioresistant malignant tumors (eg glioblastoma multiforme, melanoma) is often less effective. [0003] In order to reduce radiation damage to normal tissues around the tumor, the concept of target therapy in chemotherapy (chemotherapy) has been applied to radiation therapy; and for tumor cells with high ...
