Abstract

A column (2) suspended from the ceiling (1) of the examination room carries a board (3) on a C-curve with the image detector (4) which is based pref. on amorphous Si and is freely movable in any direction. The X-ray source (6) is attached to a parallel column (5) and adjusted by a controller (7). The position of the detector is measured by sensors (8) on its column which are connected to a computer (9). This works out a signal for the controller to reposition the X-ray source so that its beam is centred on the detector.

Description

Zur Anfertigung von Röntgenaufnahmen sind C-Bogengeräte be­ kannt, bei denen an den Enden eines C-Bogens ein Röntgen­ strahler und ein Strahlenempfänger auf einander ausgerichtet angebracht sind. Der C-Bogen ist dabei dreidimensional im Raum verstellbar. Die Ausrichtung bleibt bei der Verstellung erhalten. Der Röntgenstrahler ist aber nur in Verbindung mit dem Strahlenempfänger am C-Bogen verwendbar.C-arm devices are needed to take X-rays knows an X-ray at the ends of a C-arm radiator and a radiation receiver aligned to each other are attached. The C-arm is three-dimensional in Adjustable space. The alignment remains with the adjustment receive. The X-ray tube is only in connection with the radiation receiver can be used on the C-arm.

Der Erfindung liegt die Aufgabe zugrunde, eine Röntgenaufnah­ meeinrichtung mit einem Röntgenstrahler und einem dreidimen­ sional im Raum verstellbaren Strahlenempfänger so auszubil­ den, daß der Röntgenstrahler immer automatisch auf den Strah­ lenempfänger ausgerichtet ist, wenn mit diesem gearbeitet wird, daß er aber auch in Verbindung mit anderen Aufnahmege­ räten benutzbar ist.The invention has for its object an X-ray measuring device with an x-ray emitter and a three-dimen- sion locally adjustable radiation receiver that the X-ray emitter is always automatically on the beam oil receiver when working with it is that he is also in connection with other recording genes advise is usable.

Diese Aufgabe ist erfindungsgemäß gelöst durch die Merkmale des Patentanspruchs 1. Bei der erfindungsgemäßen Röntgenauf­ nahmeeinrichtung kann der Röntgenstrahler vom Strahlenempfän­ ger elektrisch entkoppelt werden und in Verbindung mit einem anderen Aufnahmegerät benutzt werden. Der Strahlenempfänger kann dabei vorteilhafterweise ein Festkörperdetektor auf der Basis von amorphem Silicium sein.According to the invention, this object is achieved by the features of claim 1. In the X-ray invention The X-ray source can receive the radiation receiver be electrically decoupled and in connection with a other recording device can be used. The radiation receiver can advantageously be a solid-state detector on the Base of amorphous silicon.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is based on one in the drawing illustrated embodiment explained in more detail.

In der Zeichnung ist die Decke 1 eines Untersuchungsraumes gezeigt, an der ein Stativ 2 aufgehängt ist, das eine Platte 3 mit einem Strahlenempfänger 4 trägt. Das Stativ 2 ist in Deckenschienen im Raum dreidimensional verstellbar, so daß auch der Strahlenempfänger 4, der vorteilhafterweise ein Ma­ trix-Festkörperdetektor auf der Basis von amorphem Silicium ist, frei im Raum einstellbar ist. Zur Anfertigung von Rönt­ genaufnahmen ist an der Decke 1 ein weiteres Stativ 5 aufge­ hängt, das einen Röntgenstrahler 6 verstellbar trägt. Die Verstellung des Röntgenstrahlers 6 erfolgt durch eine Steuer­ einrichtung 7.In the drawing, the ceiling 1 of an examination room is shown, on which a stand 2 is suspended, which carries a plate 3 with a radiation receiver 4 . The stand 2 is three-dimensionally adjustable in ceiling rails in space, so that the radiation receiver 4 , which is advantageously a solid-state detector based on amorphous silicon, is freely adjustable in space. For the production of X-ray gene recordings, a further stand 5 is suspended from the ceiling 1 , which carries an X-ray emitter 6 in an adjustable manner. The adjustment of the X-ray emitter 6 is carried out by a control device 7 .

Die Position des Strahlenempfängers 4 im Raum wird durch De­ tektoren 8 erfaßt, die einem Rechner 9 ein der jeweiligen Ist-Position entsprechendes Signal zuführen. Der Rechner 9 errechnet daraus ein Signal, das über die Steuereinrichtung 7 eine derartige Einstellung des Röntgenstrahlers bewirkt, daß dessen Zentralstrahl immer im Zentrum des Strahlenempfängers 4 auftrifft.The position of the radiation receiver 4 in the room is detected by detectors 8 , which supply a computer 9 with a signal corresponding to the respective actual position. From this, the computer 9 calculates a signal which, via the control device 7, causes the X-ray emitter to be set such that its central beam always strikes the center of the radiation receiver 4 .

Bei einer Verstellung der Platte 3 mit dem Strahlenempfänger 4 wird der Röntgenstrahler 6 immer nachgeführt. Der Benutzer muß also den Röntgenstrahler 6 selbst bei einer solchen Ver­ stellung nicht nachführen.When the plate 3 is adjusted with the radiation receiver 4 , the X-ray emitter 6 is always tracked. The user does not have to adjust the X-ray emitter 6 even with such a position.

Es ist möglich, die Steuereinrichtung 7 vom Rechner 9 elek­ trisch abzukoppeln, so daß der Röntgenstrahler 6 unabhängig vom Strahlenempfänger 4 auf einen anderen, nicht dargestell­ ten Strahlenempfänger, z. B. an der Wand des Untersuchungs­ raumes, eingestellt werden kann.It is possible to uncouple the control device 7 from the computer 9 , so that the x-ray emitter 6 is independent of the radiation receiver 4 on another, not shown th radiation receiver, for. B. on the wall of the examination room can be set.
