Abstract
The invention discloses an integrated porous collimator. The integrated porous collimator comprises a body and at least three through holes, the through holes penetrate through the body and are arranged to be in the shape of a honeycomb and the axes of the through holes intersect at one point. The integrated porous collimator achieves self-focusing of a radioactive source, and lays the foundation of motion focusing of the radial group.
Description
Technical field
The present invention relates to a kind of collimating apparatus, particularly relate to a kind of integrated form porous collimating apparatus.
Background technology
The mode that the focusing irradiation of existing gamma knife adopts static focus or static focus to combine with dynamic focusing.In the irradiation process of gamma knife; the selectable dirigibility of incident direction of ray had both affected the dosage gain of focus, and (incident direction is more; dosage gain is larger), also determine whether gamma knife can nimbly elude responsive organ, thereby responsive organ has been protected.The radioactive source of existing gamma knife is generally distributed on a spherical crown surface or on covering of the fan, and this has just limited the dirigibility of selecting ray incident direction.The best approach that improves the dirigibility of selection ray incident direction is to adopt single beam line, and the mode of rotating by multidimensional is carried out focusing irradiation.The maximum technology barrier that single bundle irradiates is: if adopt single collimating aperture to collimate to ray, must cause the decline (increasing of launched field penumbra) of radiation field size quality, and then affect result for the treatment of.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of integrated form porous collimating apparatus, and it forms the self-focusing of radioactive source, improves radiation field size quality, lays the first stone for the motion of ray family focuses on.
The present invention solves above-mentioned technical matters by following technical proposals: a kind of integrated form porous collimating apparatus, it is characterized in that, described integrated form porous collimating apparatus comprises body and at least three through holes, and through hole penetrates body and is arranged in cellularly, and the axes intersect of each through hole is in a bit.
Preferably, the shape of described body is right cylinder.
Preferably, the shape of described body is rectangular parallelepiped.
Preferably, described integrated form porous collimating apparatus also comprises a breach, and breach is positioned at the side of body.
Positive progressive effect of the present invention is: the present invention forms the self-focusing of radioactive source, lays the first stone for the motion of ray family focuses on, and easily aims at, and improves radiation field size quality, and simple to operate.
Brief description of the drawings
Fig. 1 is the cross-sectional view of integrated form porous collimating apparatus of the present invention.
Fig. 2 is the vertical view of integrated form porous collimating apparatus of the present invention.
Fig. 3 is the upward view of integrated form porous collimating apparatus of the present invention.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As shown in Figure 1 to Figure 3, integrated form porous collimating apparatus of the present invention comprises body 1 and at least three through holes 2, and through hole 2 penetrates body 1 and is arranged in cellularly, and the axes intersect of each through hole 2 is in a bit.The shape of body 1 can be right cylinder or rectangular parallelepiped.Integrated form porous collimating apparatus of the present invention can also comprise a breach 3, and breach 3 is positioned at the side of body 1.The effect of breach is for to collimator positioner, ensures that collimating apparatus in use can be around self axis rotation.
The corresponding radioactive source of each through hole, the axes intersect of each through hole is in a bit (focus A).This integrated form porous collimating apparatus can focus on focus after by through hole by being the radioactive ray that radioactive source family that honeycomb fashion arranges produces, and forms the self-focusing of radioactive source, lays the first stone for the motion of ray family focuses on.In sum, the present invention forms the self-focusing of radioactive source, lays the first stone for the motion of ray family focuses on, easily aim at, and simple to operate.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, the present invention has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
