Abstract
The utility model discloses a cellular radioactive source of a gamma knife. The cellular radioactive source of the gamma knife comprises a source body, a cover, and at least three through holes. The cover is arranged above the source body, and the through holes are arranged in a cellular mode in the source body. Due to the fact that the radioactive source is intensively arranged in the source body, even distribution area of the radioactive source is effectively reduced and weight of required shielding materials for the radioactive source is greatly reduced.
Description
Technical field
The utility model relates to a kind of radioactive source, particularly relates to a kind of honeycomb fashion radioactive source of gamma knife.
Background technology
The distribution of radiation of tradition gamma knife is on a large-scale sphere or fan-shaped plan, and the problem that the distribution mode of these two kinds of radioactive sources exists is, because the distribution of radiation face is larger, has increased the difficulty of shielding, causes shielding increasing considerably of weight.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of honeycomb fashion radioactive source, and it is installed radioactive source concentratedly in a source body, has effectively reduced the plain cloth area of radioactive source, has significantly reduced the weight of radioactive source shielding material requested.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of honeycomb fashion radioactive source of gamma knife, it is characterized in that, it comprises source body, gland, at least three through holes, and gland is positioned at the top of source body, and through hole is positioned at the source body and is arranged in cellular.
Preferably, described source body is shaped as right cylinder.
Positive progressive effect of the present utility model is: the utility model adopts the honeycomb fashion of concentrating to arrange radioactive source, radioactive source is installed concentratedly in a source body, effectively reduced the plain cloth area of radioactive source, significantly reduced the weight of radioactive source shielding material requested, reduced the production cost of shielding, simultaneously, because source body volume is little, can adopt the radioactive source cask transportation of standard, greatly reduce the difficulty of transportation cost and the replacing radioactive source of radioactive source.
Description of drawings
Fig. 1 is the inner structure synoptic diagram of the honeycomb fashion radioactive source of the utility model gamma knife.
Fig. 2 is the vertical view of the honeycomb fashion radioactive source of the utility model gamma knife.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As depicted in figs. 1 and 2, the honeycomb fashion radioactive source of the utility model gamma knife comprises source body 1, gland 3, at least three through holes 2, and gland 3 is positioned at the top of source body 1, and through hole 2 is positioned at source body 1 and is arranged in cellular.Source body 1 be shaped as right cylinder.Each radioactive source 4 corresponding through hole 2.Gland 3 is used for sealed source 4.
The utility model is applied in the rotatable Co 60 radiotherapy system of teetotum, radioactive source can be adopted the honeycomb fashion of concentrating arrange, radioactive source is installed concentratedly in a source body, effectively reduce the plain cloth area of radioactive source, significantly reduced the weight of radioactive source shielding material requested, reduced the production cost of shielding, simultaneously, because source body volume is little, can adopt the transportation of radioactive source cask and the stereotaxis of standard, reduced the difficulty of transportation cost and the replacing radioactive source of radioactive source.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
Claims (2)
1. the honeycomb fashion radioactive source of a gamma knife is characterized in that, it comprises source body, gland, at least three through holes, and gland is positioned at the top of source body, and through hole is positioned at the source body and is arranged in cellular.
