NEUTRON CAPTURE THERAPY SYSTEM Russian patent published in 2021 - IPC A61N5/10 

FIELD: medicine.

SUBSTANCE: suggested is neutron capture therapy system having a beam shaping unit for forming a neutron beam. The beam shaping unit has a moderator and a reflective unit surrounding the moderator. A neutron generator generates neutrons after being irradiated with a beam of charged particles. The moderator slows down the neutrons generated by the neutron generator to a predetermined energy spectrum. The reflecting unit includes a reflecting unit for deflecting neutrons back to the neutron beam and a support member for supporting the reflectors.

EFFECT: lead-antimony alloy is used in the reflector unit to reduce the creep effect that occurs when only lead material is used in reflectors, thereby enhancing the structural strength of the beam shaping unit.
