Problems solved by technology

Obviously, the structure of the neutron therapy device itself is very large. To drive the rotation of the neutron therapy device through an external rotating device must be realized by a larger rotating device than the neutron therapy device. The rotation of the device and the rotating device also requires a very large space, and the whole device is not only heavy but also has poor applicability, which is not conducive to the miniaturization of the neutron therapy device, and is also not conducive to the installation of neutron therapy equipment in hospitals
Patents CN101829409B, CN206081353U and CN206167654U provide design schemes for neutron ray rotating irradiation devices, which improve the space, weight and volume of neutron treatment terminals to a certain extent, but their cost and miniaturization design It is still not as good as the solution with fixed irradiation angle

Abstract

The invention belongs to the field of medical equipment, and discloses a neutron capturing treatment system. The neutron capturing treatment system comprises the components of an ion beam generating system which is used for supplying a stable ion beam; ion beam switching systems which are used for adjusting the direction of the iron beam to different directions, wherein at least two ion beam switching systems are arranged; neutron treatment systems which are used for irradiation treatment in different directions, wherein at least two neutron treatment systems are arranged and are in one-to-onecorrespondence with the ion beam switching systems; and treatment chambers, wherein each treatment chamber comprises at least two neutron treatment systems in different directions. According to the neutron capturing treatment system, the ion beam generating system utilizes a linear accelerator for performing ion acceleration; the ion beam switching system utilizes a deflecting magnet for performing ion beam direction adjustment; and the neutron treatment systems realize cooperation of the neutron treatment systems with different irradiation directions for use. Under a precondition that high treatment effect is ensured, miniaturization can be easily realized. The neutron capturing treatment system can be conveniently constructed in an existing hospital.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a neutron capture therapy system. Background technique [0002] The neutron source required by the Boron Neutron Capture Therapy (BNCT) device was previously provided by a reactor. Nuclear reactors themselves are expensive, and the use of nuclear reactors involves various regulations, which impose a heavy burden on doctors who perform treatment. Therefore, in order to be able to be installed in hospitals, the accelerator of the neutron therapy system needs to have the advantages of low cost and simple design, and according to the effect that boron-containing drugs can achieve in the current boron neutron capture therapy, the neutron source needs to be between 30 and A stable supply of neutron beams is maintained within 60 minutes. Therefore, medical devices that use accelerators as neutron sources for neutron capture therapy have higher stability requirements for accelerators. ...
