NEUTRON CAPTURE THERAPY SYSTEM Russian patent published in 2022 - IPC A61N5/10 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. The neutron capture therapy system contains a neutron generation device and a beam formation node, and the neutron generation device contains an accelerator and a target, while the charged particle beam generated by acceleration by the accelerator interacts with the target to generate a neutron beam, the beam formation node contains a reflector, moderator, thermal neutron absorber, radiation shield and beam output, the moderator is made with the possibility of slowing down the neutrons generated from the target to the energy range of above thermal neutrons, the reflector surrounds the moderator and is designed with the ability to direct deflected neutrons back to the moderator to increase the intensity of the beam of above thermal neutrons, the thermal neutron absorber is used to absorb thermal neutrons in order to avoid excessive dosing in surface normal tissues during treatment, the radiation shield is used to shield leaking neutrons and photons to reduce the dose of normal tissue in the area not exposed to radiation. The system contains a concrete wall forming a space for placing a neutron generation device and a beam forming unit, a support module placed in a concrete wall. The support module is capable of supporting the beam forming unit and is used to adjust the position of the beam forming unit. The support module contains concrete and a reinforcing part, at least partially, placed in concrete. The system contains an irradiation room and a charged particle beam generation room, an irradiation room and a charged particle beam generation room are spaces formed by a concrete wall, a charged particle beam generation room at least partially accommodates an accelerator. The support module and the beam forming unit are at least partially located in the partition between the irradiation room and the charged particle beam generation room.

EFFECT: application of this group of inventions will provide an improvement in the quality of the beam.
