Abstract
The present invention relates to a beam shaping device for a boron neutron capture therapy apparatus and the boron neutron capture therapy apparatus comprising same allowing a user to select the number of filter modules in advance before neutron generation and arrange same. According to the present invention, it is possible to improve a therapeutic effect and minimize side effects during boron neutron capture therapy.
Claims20
A beam shaping device for a boron neutron capture therapy apparatus comprising:
- a shielding housing comprising a space formed on a traveling path of a neutron beam;
- a target provided at a front side of the shielding housing, and configured to be irradiated with a particle beam passed through an accelerator;
- a collimator provided at a rear side of the shielding housing, and configured to adjust a region through which the neutron beam passes;
- and
- a plurality of filter modules inserted in the space and configured to decrease the energy of the neutron beam,
- wherein the plurality of filter modules, the number of which is selected by a user, are inserted in the shielding housing.
A boron neutron capture therapy apparatus comprising:
- an accelerator configured to accelerate a particle beam;
- a target configured to be irradiated with the particle beam accelerated in the accelerator and release neutrons;
