Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
In order to so more preferable that understand technical solution of the present invention, applicant illustrates the hair by the specific embodiment of Fig. 1
The treatment head of bright radiation source assemblies and gamma knife.Fig. 1 is the schematic cross-sectional view of radiation source assemblies provided in an embodiment of the present invention.
As shown in Figure 1, the radiation source assemblies of present embodiment include a roller 10, radioactive source fixed blocks 20, a multiple radioactive sources
30, two shielding slabs 40 and two bearings 50.Roller 10 is cylindrical, has the side wall 12 of its parallel axis, by the side wall 12
The cavity 14 and multiple ray channels 16 through the side wall 12 surrounded.Radioactive source fixed block 20 is housed in the cavity 14,
On offer multiple accepting holes 22 through its own.The side of radioactive source 30 is bonded with the side wall 12 of roller 10, and is accommodated
The opening that the inner wall of cavity 14 is close in hole 22 is respectively corresponded with ray channel 16.In this way, the ray that radioactive source 30 issues can pass through
Linear ray channel 16 projects except roller 10.Preferably, the side wall 12 of the roller 10 where ray channel 16 in diameter
Upward thickness is less than the thickness of the side wall of the opposite other side.In this way, being conducive to the injection of ray, it is also beneficial to the shown other side
Preferably shield ray.Shielding slab 40 is arranged in 20 two sides of radioactive source fixed block and is located at axial direction with the cavity 14 of sealed cylinder 10
Two sides.In this way, radiation source assemblies form a whole.In the present embodiment, radioactive source 30 is cobalt source, the radioactive source fixed block
20 are also referred to as cobalt source fixed block.
It is the schematic cross-sectional view of the treatment head of gamma knife provided in an embodiment of the present invention incorporated by reference to Fig. 2 and 3, Fig. 2, Fig. 3 is
The treatment head of Fig. 2 is located at the schematic cross-sectional view of another state.The treatment head of gamma knife includes shield 60, collimator 70 and such as
Radiation source assemblies shown in FIG. 1.Preferably, the treatment head of gamma knife further includes the cabinet 80 for coating shield 60, with protection screen
Cover body 60.Shield 60 is made of shielding material, such as lead, forms columned reception room 64 and multiple is connected to reception room 64
To external through-hole 62.Collimator 70 has multiple collimating apertures 72.Radiation source assemblies as shown in Figure 1 are by being sheathed on the roller
Bearing 50 (as shown in Figure 1) on the lateral wall 12 of 10 axial endses can be rotationally housed in reception room 64 along its axis.It puts
The settable driving wheel 18 as shown in Figure 1 in axial side for penetrating source component, is connected to a driving device, such as motor.In this way,
Under the driving of the driving device, roller 10 can turn to the first position corresponding with through-hole 62 of ray channel 16 (such as Fig. 2 institute
Show) and make radioactive source 30 in the open state；Roller 10 also can turn to ray channel 16 and is staggered with the through-hole 62 (such as mistake
Open 180 degree) the second position and radioactive source 30 is in close state.Collimator 70 is when roller 10 is located at the first position
It is moved to the third place corresponding with through-hole 62 of collimating aperture 72, to realize treatment；It is also mobile at 10 second positions of roller
The 4th position that the collimating aperture 72 through-hole 62 is staggered, to terminate to treat.
The treatment head of the gamma knife of this implementation by the way of rotary emission source component due to implementing to radioactive source 30
Open or close, make collimate pass source dislocation distance stroke shorten, to keep equipment overall volume small, overall weight becomes smaller.Screen
Cover material reduction.In addition, focus fixed range of the exit end face of collimating aperture 72 to radioactive source 30, is meeting end face shielding requirements
In the case of, Distance Shortened of the source to focus, the raising of focus dosage rate may be implemented by rotating pass source roller 10.
