Description

Support structure of neutron generation system and neutron capture treatment system Technical Field The present utility model relates to a radiation irradiation system, and more particularly, to a support structure of a neutron generating system and a neutron capturing treatment system. Background With the development of atomic science, radiation therapy such as cobalt sixty, linac, electron beam, etc. has become one of the main means for cancer therapy. However, conventional photon or electron therapy is limited by the physical condition of the radiation itself, and damages a large amount of normal tissues on the beam path while killing tumor cells, and in addition, due to the difference of sensitivity of tumor cells to radiation, the conventional radiation therapy often has poor therapeutic effects on malignant tumors with relatively high radiation resistance (such as glioblastoma multiforme (glioblastoma multiforme) and melanoma (melanoma)). In order to reduce radiation damage to normal tissue surrounding a tumor, the concept of target therapy in chemotherapy (chemotherapy) is applied to radiotherapy, and radiation sources with high relative biological effects (relative biological effectiveness, RBE) such as proton therapy, heavy particle therapy, neutron capture therapy, etc. are also actively developed for tumor cells with high radiation resistance. The neutron capture treatment combines the two concepts, such as boron neutron capture treatment, and provides better cancer treatment selection than the traditional radioactive rays by means of the specific aggregation of boron-containing medicaments in tumor cells and the accurate neutron beam regulation. Various radioactive rays, such as neutrons and photons with low to high energy, are generated in the radiotherapy process, and may cause different degrees of damage to normal tissues of a human body. In the field of radiotherapy, radiotherapy equipment is usually placed in a building with a concrete structure, radiation possibly generated by the equipment is isolated, and a beam shaping device is additionally arranged for adjusting energy of a beam, so that the radiation therapy equipment can effectively treat and reduce radiation pollution of the environment and other non-therapeutic parts. How to set the position of the radiation exposure system in a concrete-structured building and how to install the fixed radiation exposure system will have a great impact on whether an effective treatment is achieved and on ensuring the radiation safety. Disclosure of Invention Currently, for a radiation irradiation system with a beam emitted in a horizontal direction, an installation scheme is adopted in which a beam shaping device is embedded into a side wall of a building, and the wall itself can provide support for the beam shaping device. But for a vertically outgoing radiation irradiation system the above-described wall support solution will no longer be applicable. Therefore, the inventor provides a support structure of a neutron generation system and a neutron capture treatment system, which can meet the requirement of mounting and supporting a beam shaping body and a beam transmission structure in the vertical direction and realize the neutron capture treatment in the vertical direction. The object of the utility model can be achieved by the following scheme: The utility model provides a support structure of a neutron generation system, which is used for supporting the neutron generation system, the neutron generation system comprises a beam transmission structure and a beam shaping body, the support structure of the neutron generation system comprises a first support component, the first support component is connected with the top of a treatment room, and the first support component is at least used for partially supporting the beam shaping body.
