Abstract: A neutron capture therapy system is provided, which may prevent a material of a beam shaping assembly from deformation and damaged, and improve the flux and quality of neutron sources. A boron neutron capture therapy system (100) includes a neutron generating device (10) and a beam shaping assembly (20). The neutron generating device (10) includes an accelerator (11) and a target (T). A charged particle beam (P) generated by acceleration of the accelerator (11) acts with the target (T) to generate neutrons. The neutrons form a neutron beam (N). The neutron beam (N) defines a main axis (X). The beam shaping assembly (20) includes a support part (21) and a main part (23) filled within the support part (21).

Abstract: A neutron capture therapy system includes a neutron generation device for generating a neutron beam, an irradiation room for irradiating an irradiated body with the neutron beam and a placement table that is accommodated in the irradiation room and is adapted to support the irradiated body. The placement table includes a placement member for supporting a patient, an adjustment device for adjusting a spatial position of the placement member, a driving rod connected between the adjustment device and the placement member and a first shielding member covering the adjustment device. The first shielding member prevents the adjustment device from being radiated by radioactive rays. The adjustment device is disposed in the first shielding member that is basically sealed, thereby greatly reducing radiation damage to the adjustment device by neutrons and gamma rays and prolonging the service life of the adjustment device.

Abstract: A neutron capture therapy system is provided, including a neutron generating device and a beam shaping assembly. The neutron capture therapy system further includes a concrete wall forming a space for accommodating the neutron generating device and the beam shaping assembly and shielding radiations generated by the neutron generating device and the beam shaping assembly. A support module is disposed in the concrete wall, the support module is capable of supporting the beam shaping assembly and is used to adjust the position of the beam shaping assembly, and the support module includes concrete and a reinforcing portion at least partially disposed in the concrete. The neutron capture therapy system designs a locally adjustable support for the beam shaping assembly, so that the beam shaping assembly can meet the precision requirement, improve the beam quality, and meet an assembly tolerance of the target.
