Embodiment Construction

[0019] 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. Set XYZ where the direction of the charged particle beam P emitted from the accelerator described later is the X axis, the direction perpendicular to the direction of the charged particle beam P emitted from the accelerator is the Y axis, and the direction perpendicular to the ground is the Z axis. coordinate system (reference figure 2 and image 3 ), and use X, Y, and Z in the description of the positional relationship of each component.

[0020] Such as figure 1 , the neutron capture therapy system in this embodiment is preferably a boron neutron capture therapy system 100, and the boron neutron capture therapy system 100 is a device for cancer treatment using boron neutron capture therapy. Boron neutron capture therapy performs cancer treatment by irradi...

Abstract

The invention relates to a neutron capture therapy system. The neutron capture therapy system comprises an accelerator, a beam transmission assembly and neutron beam generation parts; the acceleratoraccelerates charged particles to generate charged particle beams, the beam transmission assembly transmits the charged particle beams generated by the accelerator to the neutron beam generation parts,the neutron beam generation parts generate neutron beams for therapy, shielding walls are arranged between the neutron beam generation parts and the accelerator so that the problems can be solved that an operation personnel is radiated by neutrons and other rays which leak from the neutron beam generation parts during maintenance of the accelerator, and the activation reaction of the acceleratoris reduced.

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...
