Verfahren zur Herstellung vom Röntgenbildern.
EMI1.1
<Desc/Clms Page number 2>
werden schon infolge des Compton-Effektes im Objekt 3 weichere Strahlen erzeugt, die Elektronenstrahlen kleinerer Geschwindigkeit auslösen und infolge der Vereinigung derselben in einer andern Bildebene die Figur in S unscharf machen wurden. Um diese Strahlen unschädlich zu machen, ist ein Gitter 10' vor der Elektronenoptik angeordnet, an das durch eine Spannungsquelle 11 eine Bremsspannung gelegt wird, die das Durchtreten der langsameren Elektronenstrahlen verhindert.
Da sich elektronenoptisehe Systeme verschiedener Dispersen herstellen lassen, können durch Kombination solcher verschiedener Systeme Einrichtungen getroffen werden, die in ihrer Wirkung achromatischen Linsensystemen entsprechen, so dass trotz der verbleibenden Unterschiede in der Elektronengeschwindigkeit vollkommen scharfe Bilder erhalten werden.
PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Röntgenbildern, dadurch gekennzeichnet, dass die durch den zu untersuchenden Körper hindurchgegangenen bzw. von diesem ausgehenden Röntgenstrahlen an einer Vakuumgrenzschicht in Elektronenstrahlen umgewandelt und diese dann zur Erlangung eines Bildes elektronenoptisch beeinflusst werden.

EMI1.1
<Desc / Clms Page number 2>
As a result of the Compton effect, softer rays are generated in the object 3, which release electron rays at a lower speed and, as a result of their union in another image plane, would make the figure in S blurred. In order to render these rays harmless, a grid 10 'is arranged in front of the electron optics, to which a voltage source 11 applies a braking voltage that prevents the slower electron beams from passing through.
Since electron-optical systems of different disperses can be produced, devices can be created by combining such different systems which correspond in their effect to achromatic lens systems, so that completely sharp images are obtained despite the remaining differences in the electron speed.
PATENT CLAIMS:
1. A method for producing X-ray images, characterized in that the X-rays which have passed through or emanate from the body to be examined are converted into electron beams at a vacuum boundary layer and these are then electronically influenced to obtain an image.
