Title:
NEUTRON CAPTURE THERAPY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/042137
Kind Code:
A1
Abstract:
Provided is a neutron capture therapy system, comprising a beam-shaping body, and a vacuum tube and at least one cooling device, which are arranged in the beam-shaping body, wherein the beam-shaping body comprises a beam inlet, an accommodation cavity accommodating the vacuum tube, a retarder, which is adjacent to an end portion of the accommodation cavity, a reflector surrounding the retarder, and a radiation shield and a beam outlet arranged in the beam-shaping body; an end portion of the vacuum tube is provided with a target material; the cooling device is used for cooling the target material; the target material undergoes a nuclear reaction with a charged particle beam incident from the beam inlet so as to produce neutrons; the retarder decelerates the neutrons produced by the target material to an epithermal neutron energy region; the reflector leads deviating neutrons back to the retarder to enhance the intensity of an epithermal neutron beam; at least one accommodation pipeline accommodating the cooling device is further arranged in the beam-shaping body; and a filler is filled between the cooling device and an inner wall of the accommodation pipeline.
