Abstract
The present disclosure provides a beam shaping assembly for neutron capture therapy, wherein the beam shaping assembly includes a neutron generating device, a moderator, a disturbing unit and a beam outlet. The neutron generating device is used to generate neutrons that form a neutron beam in a direction from the neutron generating device to the beam outlet, the moderator adjacent to the neutron generating device for adjusting fast neutrons in the neutron beam to epithermal neutrons. The disturbing unit is located between the moderator and the beam outlet for passing through the neutron beam and reducing the gamma ray content in the neutron beam passing through the beam outlet. The technical solution provided by the present disclosure can effectively reduce the gamma ray content in the neutron beam under the premise that the quality of the neutron beam is not significantly adversely affected.
