Description
Technical field
The utility model relates to field of radiation therapy, especially a kind of adjustable MNSR Reactor neutron therapy device in output aperture
Channel design.
Background technique
Neutron therapy, that is, boron neutron capture therapy.Boron neutron capture therapy by the nuclear reaction in tumour cell come
Destroy cancer cell.Its principle is such that this compound and cancer are thin first to a kind of special compound of boracic of patient injection
Born of the same parents have very strong affinity, into after human body, be gathered in cancer cell rapidly, and distribution is seldom in its hetero-organization.This boracic
Compound is non-toxic to humans, to cancer also without therapeutic effect.At this moment, it is irradiated with a kind of neutron ray, this ray
It is little to the damage of human body, but very strong nuclear reaction can occur for neutron and the boron entered in cancer cell, release a kind of lethality
The range of extremely strong ray, this ray is very short, the length of only one cancer cell.So only killing cancer cell, week is not damaged
Enclose tissue.This technology for selectively only killing complex-shaped cancer cell without damaging normal tissue, referred to as boron neutron are captureed
Obtain treatment technology.
Application No. is a kind of neutron therapy devices of 201620696868.4 utility model and the utility model technical field
It is identical.A kind of this entitled utility model of neutron therapy device includes beam-shaping body, the neutron in beam-shaping body
Generating unit, the tube bank that ion beam is sent to neutron generating unit, the deflection electromagnet that direction of beam transport is changed
And collimator, the beam-shaping body include slow body and the reflector for being packaged in slow external week, the neutron generating unit
Generate neutron after ion beam irradiates, the slow body is described by from the neutron degradation that neutron generating unit generates to default power spectrum
The neutron that reflector will deviate from is led back to improve the neutron intensity in default power spectrum, and the tube bank has axis, and the beam is whole
Body can rotate and carry out to irradiated body the irradiation of different angle around the axis of tube bank.Pass through support frame, beam-shaping body
And the setting of deflection magnet makes entire neutron therapy device only and need to rotate self structure to be just able to achieve entire neutron therapy device
The irradiation of different angle is carried out, structure is simple, operates light, it is easy to accomplish.
The aperture of the sub-channel end of the neutron therapy device generally used now is not adjustable.Though the above-mentioned prior art
So realize that entire neutron therapy device carries out the irradiation of different angle, structure is simple, operates light, it is easy to accomplish, but can not
It solves the above problems.
