Neutron capture therapy system

Abstract

The invention provides a neutron capture therapy system. The neutron capture therapy system can effectively utilize space and conduct therapy on multiple patients at the same time, does not elongate the beam transmission path excessively and thus has low loss. The neutron capture therapy system comprises an accelerator, a beam transmission assembly and neutron beam generation parts, wherein the accelerator accelerates 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 part, and the neutron beam generation parts generate neuron beams for therapy and comprise a first neuron beam generation part, a second neutron beam generation part and a third neutron beam generation part; the beam transmission assembly comprises a first transmission part, a beam direction converter, a second transmission part, a third transmission part and a fourth transmission part, wherein the first transmission part is connected with the accelerator, the beam direction converter switches the heading direction of the charged particle beams, and the second transmission part, the thirdtransmission part and the fourth transmission part transmit the charged particle beams from the beam direction converter to the first neutron beam generation part, the second neutron beam generation part and the third neutron beam generation part respectively, two of the first transmission part, the third transmission part and the fourth transmission part define a first plane, the first transmission part and the second transmission part define a second plane, and the first plane is different from the second plane.

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...

Problems solved by technology

At the same time, currently in the accelerator boron neutron capture therapy, multiple patients cannot be treated at the same time, or the layout of multiple irradiation rooms is unreasonable, and the transmission path of the charged particle beam is long, resulting in loss
