das abzubildende Objekt zentriert ausgerichtet Die Röntgenröhren können auch mit Hilfe einer mechanischen Blendenanordnung gesteuert werden. Zur Ausblendung der getrennten Perspektivbilder werden die Strahlen der Einzelröhre durch Blendenvorrichtungen begrenzt, womit beliebige Objektgrößen ausgeblendet werden können und der Röntgenfilm optimal ausgenutzt werden kann.the object to be imaged is centered X-ray tubes can also be controlled with the aid of a mechanical aperture arrangement. To hide the separate perspective images, the Beams of the single tube are limited by aperture devices, with which any object sizes are masked out and the X-ray film can be optimally used.

For the sake of clarity, the arrangement is only described in one dimension. The individual tubes 14i, 142 and i4i of the subgroup 14 and the subgroup 15 of the entire multiple radiation source arrangement 13 are aligned with the object 19. The middle object layer 19 '(position, size) is displayed with optical aids (light sighting). Perspective images are recorded separately in the recording plane 20. The beam is masked out with the diaphragm arrangement 13 '. With this aperture an exposure control came / in principle also be carried out.

Die Streustrahlung 37 des Objektes 35 wird mit Hilfe der zur Strahlungsquelle ausgerichteten und gegebenenfalls fokussierten Streustrahlenraster 32", 33" und 34" unterdrückt. Die einzelnen Streustrahlenraster sind miteinander verbunden (38) und können, um die Rasterstruktur zu verwischen, während der Aufnahme zur Aufnahmeebene (36) bewegt (39) werden. Die Streustrahlenraster-Anordnung kann ebenfall' ro gewählt werden, daß dieF i g. Figure 6 shows an anti-scatter grid arrangement for a multiple beam arrangement emerging from the tubes 32, 33 and 34. The tubes are directed at the object 35 and generate 36 in the recording plane the separate perspective images 32 ', 33' and 34 '. The scattered radiation 37 of the object 35 is with the help of the for Anti-scatter grids 32 ", 33" and 34 "aligned with the radiation source and optionally focused. The individual anti-scatter grids are connected to one another (38) and can be arranged around the grid structure to blur while recording to the recording plane (36) are moved (39). The anti-scatter grid arrangement can also be chosen that the Raster, deren Lamellen linear angeordnet und zur Strahlenquelle gerichtet sind, alle in einer Ebene angeordnet sind.Grids, the lamellas of which are arranged linearly and directed towards the radiation source, are all arranged in one plane.
