Title:
NEUTRON CAPTURE THERAPY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/114308
Kind Code:
A1
Abstract:
A neutron capture treatment system (100), comprising an accelerator (200) for use in generating a charged particle beam (P), a neutron generating portion (10) that reacts with the charged particle beam (P) to generate a neutron beam (N), and a beam shaping body (20); the beam shaping body (20) comprises an accommodating portion (21), a speed reducing body (22), a reflecting body (23), a thermal neutron absorbing body (24), a radiation shield (25) and a beam exit port (26); the accommodating portion (21) is provided with a vacuum tube (30) that is connected to the accelerator (200), the vacuum tube (30) transmitting the charged particle beam (P) that is accelerated by the accelerator (200) to the neutron generating portion (10) such that the neutron generating portion (10) and the charged particle beam (P) generate neutrons; the neutron generating portion (10) moves between a first position and a second position, and in the first position, the neutron generating portion (10) may react with the charged particle beam (P) to generate neutrons, while, in the second position, the neutron generating portion (10) detaches from the beam shaping body (20), which is to say that disassembling a part of the vacuum tube (30) that is provided with the neutron generating portion (10) causes the neutron generating portion (10) to detach from the beam shaping body (20), thereby reducing the direct contact between workers and the generating portion (10) following a nuclear reaction, and reducing radiation safety hazards for the workers.
