发明名称 Multiple source esp. for three=dimensional X=ray image - has movable aperture plates for selecting some parts of source only
摘要 <p>An appts. sub-divides an X-ray beam or the like issuing from a multiple source into radiation sub-groups. The individual radiation sources of the multiple source are simultaneously switched on and the radiation, before it reaches the object under investigation, passes through a light stop which is moved in different positions at different timers relative to the source; this causes only certain rays to pass through. Used for three-dimensional X-ray images in coded for which are to be reconstituted by tomosynthesis. By moving the light stop or aperture plate into different positions at different times, the need to switch on and off individual light sources is eliminated and the process is thus considerably simplified.</p>
