Problems solved by technology

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 of more radiation-resistant malignancies (eg, glioblastoma multiforme, melanoma) is often less effective

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0033] Such as image 3 , 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. The accelerator 11 accelerates charged particles (such as protons, deuterium nuclei, etc.) to generate charged particle beams P such as proton beams. The charged particle beams P irradiate the target material T and interact with The target T produces neutrons, and the neutrons form a neutron beam N, and the neutron beam N defines a main axis X, and the target T is preferably a metal target. The direction of the neutron beam N shown in the figure and described below does ...

Abstract

Disclosed is a neutron capture therapy system and a beam shaping body for the same. The neutron capture therapy system is capable of preventing a beam shaping body material from being damaged due to deformation and improving the flux and quality of a neutron irradiation source. The neutron capture therapy system disclosed by the present invention includes a neutron generation device and a beam shaping body; the neutron generation device includes an accelerator and a target; a charged particle beam generated by the acceleration of the accelerator acts with the target to generate neutrons forming a neutron beam, and a principal axis is limited by the neutron beam; and the beam shaping body includes a supporting part and a main part filled in the supporting part.

Description

technical field [0001] One aspect of the present invention relates to a radiation irradiating system, in particular to a neutron capture therapy system; another aspect of the present invention relates to a beam shaping body for a radiation irradiating system, in particular to a neutron Capture the beam shaper of the 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 o...
