Description

  Röntgenröhre. 
 EMI1.1 
 wird, so dass sie nach Art einer Lochkamera wirkt, Fig. 5. Durch diese Einrichtung werden alle vagabundierenden Strahlen geblendet, während die durch die Öffnung durchtretenden, also in derselben sich kreuzenden und daher gewissermassen von einem sehr kleinen   Projektionszentrum   ausgehenden Strahlen, allein für die Bilderzeugung ausschlaggebend sind. 



   Vergrösserte, verkleinerte oder parallel projektivische Darstellungen kann man durch diese Erfindung so erreichen, dass vor die Antikathode innerhalb oder ausserhalb der Röhre ein mitrailleusenartiger Raster gesetzt wird, der aus einzelnen, durch eine aus einer strahlenundurchlässigen oder wenigstens Strahlen stark absorbierenden Masse verbundenen Röhrchen besteht. Die einzelnen Röhrchen des Rasters stehen je nachdem, ob man ver- grösserte, verkleinerte oder parallel projektivische Darstellungen erreichen will, divergent, konvergent oder parallel.

   Mit dieser Einrichtung können aber nicht nur beliebig ver-   grössere,   verkleinerte   o {1el' gleich   grosse Aufnahmen erzeugt werden, sondern es kann ent-   weder durch Verwendung eines parallelen Rasters eine parallele Durchstrahlung eines Körpers erreicht werden, so dass die in den verschiedenen Tiefen gegebenen Dosen sich nur mehr graduell durch den Absorptionsverlust unterscheiden oder durch Verwendung eines konvergierenden Rasters sogar in der Tiefe grössere Dosen als an der Oberfläche gegeben werden. Mit konvergierender Strahlung kann auch das Projektions zentrum in den Körper hinein verlegt werden, so dass isolierte Bilder von sonst sich deckenden Organen erzielt   werden können.

 so that it acts like a pinhole camera, Fig. 5. All stray rays are blinded by this device, while the rays passing through the opening, i.e. crossing in the same and therefore to a certain extent emanating from a very small projection center, are solely for the Image generation are crucial.



   Enlarged, reduced or parallel projective representations can be achieved by this invention in such a way that a mitrailleusen-like grid is placed in front of the anticathode inside or outside the tube, which consists of individual tubes connected by a mass that is radio-opaque or at least highly absorbent. The individual tubes of the grid are divergent, convergent or parallel, depending on whether you want to achieve enlarged, reduced or parallel projective representations.

   With this device, however, not only arbitrarily enlarged, reduced images of the same size can be produced, but a parallel irradiation of a body can be achieved either by using a parallel grid, so that the given in the different depths Doses differ only gradually in terms of the absorption loss or, by using a converging grid, even larger doses in depth than are given on the surface. With converging radiation, the projection center can also be moved into the body, so that isolated images of organs that otherwise overlap can be achieved.

   In FIG. 1 the tubes are arranged diverging, in FIG. 2 parallel to one another, in FIG. 8 converging. Fig. 4 shows the application in stereoscopic recording, and shows that the recordings

Claims (1)

2. Röntgenröhre nach Anspruch l, dadurch gekennzeichnet, dass aus dem diffusen Röntgenstrahlenbündel durch Einschaltung divergierender, konvergierender oder paralleler Robrraster diejenigen Strahlen abgeblendet werden, welche nicht zur Erzeugung des Röntgenbildes dienen sollen (Fig. 1 bis 4). 2. X-ray tube according to claim l, characterized in that those rays are masked out of the diffuse X-ray beam by switching on diverging, converging or parallel Robrraster, which should not be used to generate the X-ray image (Fig. 1 to 4). 3. Röntgenröhre nach Anspruch 1 mit einer Blende im Innern der Röhre, dadurch gekennzeichnet, dass die Röntgenstrahlen durch ein enges Loch der Blende gehen, das nach Art einer Lochkamera wirkt (Fig. 5). 3. X-ray tube according to claim 1 with a diaphragm inside the tube, characterized in that the X-rays go through a narrow hole in the diaphragm which acts like a pinhole camera (Fig. 5).
