Title:
NEUTRON CAPTURE THERAPY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/114307
Kind Code:
A1
Abstract:
The present application provides a neutron capture treatment system, comprising a beam shaping body and a vacuum tube arranged in the beam shaping body, wherein the beam shaping body comprises a beam inlet, a receiving chamber for accommodating the vacuum tube, a retarding body adjacent to the end of the receiving chamber, a reflector surrounded by the retarding body, a radiation shield arranged inside the beam shaping body, and a beam exit, the end of the vacuum tube is provided with a target material, the target material reacts with a charged particle beam incident from the beam inlet to generate neutrons, the neutrons then form a neutron beam, and the neutron beam exits the beam exit and defines a neutron beam axis, the retarding body decelerates the neutrons generated from the target material to a superheated neutron energy region, the reflector guides deviated neutrons back to the retarding body, the radiation shield is used to shield leaking neutrons and photons, the retarding body comprises at least two cylindrical retarding bodies having different outer diameters, the retarding body has a first end adjacent the beam inlet and a second end adjacent the beam exit, and the target material is received between the first end and the second end.
