Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, the present invention will be further described in detail.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1 to Fig. 3, present embodiment adopts the following technical scheme that a kind of ray with anti-scatter function is quasi-
Straight device, it includes ray tube 1, x-ray source 2, ray window 3, first constrains the constraint of mold 4, second mold 5, third constrains
