Embodiment Construction

[0023] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement them with reference to the description.

[0024] like figure 1 , the neutron capture therapy system in this embodiment is preferably a boron neutron capture therapy system 100 , including a neutron generator 10 , a beam shaper 20 , a collimator 30 and a treatment table 40 . The neutron generating device 10 includes an accelerator 11 and a target T, and the accelerator 11 accelerates charged particles (such as protons, deuterons, etc.) to generate charged particle beams P such as proton beams, and the charged particle beams P irradiate the target material T and interact with them The target T acts to generate neutron rays (neutron beams) N, and the target T is preferably a metal target. Select the appropriate nuclear reaction based on the required neutron yield and energy, the available accelerated c...

Abstract

The invention provides a neutron capture treatment system. The neutron capture treatment system comprises a neutron generation device and a beam shaping body, and further comprises a concrete wall which forms a space for accommodating the neutron generation device and the beam shaping body and shields radiation generated by the neutron generation device and the beam shaping body, wherein a supporting module is arranged in the concrete wall; the supporting module can support the beam shaping body and is used for adjusting the position of the beam shaping body; and the supporting module comprises concrete and a reinforcing part at least partially arranged in the concrete. According to the neutron capture treatment system, a locally adjustable support is designed for the beam shaping body, sothat the beam shaping body meets the precision requirement, the beam quality is improved, and the assembly tolerance of a target is met.

Description

technical field [0001] The invention relates to a radiation 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 radiat...
