A neutron-capture therapy system includes a charged particle beam generation unit, a beam transmission unit and a neutron beam generation unit. The charged particle beam generation unit includes an ion source and an accelerator. The accelerator accelerates charged particles generated by the ion source, so as to obtain a charged particle beam of the required energy. The neutron beam generation unit includes a target, a beam shaping body and a collimator. The charged particle beam irradiates onto the target through the beam transmission unit to generate neutrons, which sequentially pass through the beam shaping body and the collimator to form a neutron beam for therapy. The neutron-capture therapy system is accommodated in a concrete building including an irradiation room, an accelerator chamber and a beam transmission chamber. The neutron beam generation unit is at least partially accommodated in a partition wall of the irradiation chamber and the beam transmission chamber.

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.

According to one aspect, the present description concerns a target (20) for the production of nuclear particles. The target comprises a shell (24) formed by a surface of revolution and mounted in rotation about an axis of rotation (21) that coincides with an axis of revolution of the shell. The target further comprises a reservoir comprising a target material in the liquid state during use, the target material being suitable for producing the nuclear particles; a target material raising device configured to entrain, in operation, the target material from the reservoir toward an upper surface (244) of the shell; a gutter formed along an external perimeter (245) of the shell and configured to receive, in operation, droplets derived from a film (22) of target material induced by centrifugal action on said upper surface of the shell as the shell is rotated; at least one return pipe forming a fluid connection between the gutter and the container; an inlet pipe configured, in operation, to let in a beam of accelerated particles into a zone of impingement of said accelerated particles with the shell, said zone of impingement being situated on said upper surface of the shell, the interaction of said accelerated particles with the target material circulating on said upper surface of the shell generating said nuclear particles

A boron neutron capture therapy system includes a neutron capture therapy device, a photon emission detection device and a treatment bed. The photon emission detection device includes a detecting portion surrounding the periphery of the treatment bed and detecting gamma rays generated after irradiating a boron-containing drug with neutrons; the detecting portion includes a first detecting portion and a second detecting portion moving away from or close to the first detecting portion so that the detecting portion forms a ring with the radius being increased or decreased; and the ring surrounds the treatment bed. The photon emission detection device for use in the boron neutron capture therapy system can change the radius of the ring, surrounding an irradiated object, of the detecting portion according to the actual condition in the boron neutron capture therapy so as to improve the detection precision of the photon emission detection device.
