Abstract

The x-ray image amplifier includes an optical transmitter for transmitting a light bundle. The light bundle is focused on an x-ray device opposite an x-ray image amplifier. The optical transmitter includes four laser diodes which are arranged at 90 degrees w.r.t. each other around the x-ray image amplifier. Each laser diode is associated with a controllable positioning device so that when the distance between the x-ray generator and the x-ray image amplifier changes, or when the x-ray bundle changes, a matching light bundle is generated. The x-ray generator and the image amplifier are located against C-arc.

Description

Aus dem deutschen Gebrauchsmuster 88 06 671 ist ein Röntgen­ diagnostikgerät mit an einer Halterung einander gegenüberlie­ gend angeordneten Röntgenstrahler und Röntgenbildverstärker bekannt. Am Röntgenbildverstärker ist als Positionierhilfe ein Lichtsender zum Kennzeichnen des Zentralstrahlbereiches eines vom Röntgenstrahler ausgesandten Röntgenstrahlenbündels vorgesehen. Als Lichtsender können ein erster und ein zweiter um 90° zueinanderversetzte Lichtsender vorgesehen sein, die jeweils einen Fächerstrahl aussenden. Die Lichtfächer kreuzen sich hierbei im Zentralstrahl des Röntgenstrahlenbündels. Es ist bekannt, den Lichtsender als Laserlichtquelle auszufüh­ ren.An X-ray is from German utility model 88 06 671 Diagnostic device with each other on a holder X-ray emitter and X-ray image intensifier arranged accordingly known. On the X-ray image intensifier is a positioning aid a light transmitter for marking the central beam area an X-ray beam emitted by the X-ray emitter intended. A first and a second can be used as light transmitters light transmitters offset from one another by 90 ° are provided each send out a fan beam. Cross the light fans in the central beam of the X-ray beam. It is known to design the light transmitter as a laser light source ren.

Aufgabe der Erfindung ist es, eine Röntgendiagnostikeinrich­ tung mit einer Positionierhilfe derart auszuführen, daß eine Positionierung von Röntgenstrahler und Röntgenbildverstärker in Bezug zu einem Untersuchungsobjekt möglich ist, ohne daß hierbei Röntgenstrahlung erforderlich ist.The object of the invention is an X-ray diagnostic device device with a positioning aid so that a Positioning of the X-ray source and X-ray image intensifier in relation to an object under investigation is possible without X-rays are required.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Pa­ tentanspruches 1 gelöst.The object is achieved by the features of Pa claim 1 solved.

Vorteil der Erfindung ist, daß durch das Vorsehen des Licht­ senders am Röntgenbildverstärker insbesondere bei einer Posi­ tion, bei der sich der Röntgenbildverstärker über einem Un­ tersuchungstisch befindet, nunmehr ein Lichtbündel auf das Untersuchungsobjekt gerichtet ist, das einem vom Röntgen­ strahler ausgehenden Röntgenstrahlenbündel entspricht. Das durchleuchtete Feld wird durch Projektion des Lichtbündels auf das Objekt nunmehr sichtbar, so daß eine Positionierung ohne Röntgenstrahlung erfolgen kann.Advantage of the invention is that by providing the light transmitter on the X-ray image intensifier, especially for a posi tion, in which the X-ray image intensifier is above an Un examination table is now a light beam on the Examination object is directed from the X-ray radiator outgoing X-ray beam corresponds. The Illuminated field is created by projecting the light beam now visible on the object, so that positioning can be done without X-rays.

Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispie­ les anhand der Zeichnung in Verbindung mit den Unteransprü­ chen.Further advantages and details of the invention emerge from the following description of an exemplary embodiment les based on the drawing in conjunction with the dependent claims chen.

Das in der Figur gezeigte Röntgendiagnostikgerät 1 ist bei­ spielsweise als fahrbares Röntgendiagnostikgerät ausgeführt und besitzt einen Röntgenstrahler 3 und einen Röntgenbildver­ stärker 4, die an den Enden eines C-Bogens 2 einander gegen­ überliegend, angeordnet sind. Gemäß der Erfindung ist am Röntgenbildverstärker 4 ein Lichtsender 5 vorgesehen, dessen Lichtbündel 6 auf den Röntgenstrahler 3 fokussiert ist. Vor­ zugsweise ist hierbei das Lichtbündel 6 so eingeblendet, daß es einem vom Röntgenstrahler 3 ausgehenden Röntgenstrahlen­ bündel entspricht. Bei fest vorgegebenen Abstand zwischen Röntgenstrahler 3 und Röntgenbildverstärker 4, ist eine ein­ malige Justierung des Lichtsenders 5 ausreichend. Kann aber der Abstand zwischen dem Röntgenstrahler 3 und dem Röntgen­ bildverstärker 4 oder der Öffnungswinkel des Röntgenstrahlen­ bündels verändert werden, so ist es günstig, wenn auch das Lichtbündel 6 entsprechend verändert werden kann, was durch entsprechende Einblendung oder Justage des Lichtbündels 6 auf den Fokus des Röntgenstrahlers 3 möglich ist.The X-ray diagnostic device 1 shown in the figure is designed for example as a mobile X-ray diagnostic device and has an X-ray emitter 3 and an X-ray image intensifier 4 , which are arranged opposite one another at the ends of a C-arm 2 . According to the invention, a light transmitter 5 is provided on the X-ray image intensifier 4 , whose light bundle 6 is focused on the X-ray emitter 3 . Before preferably the light beam 6 is faded in such a way that it corresponds to an X-ray beam emitted by the X-ray emitter 3 . If the distance between the X-ray emitter 3 and the X-ray image intensifier 4 is fixed, a one-time adjustment of the light transmitter 5 is sufficient. However, if the distance between the X-ray emitter 3 and the X-ray image intensifier 4 or the opening angle of the X-ray beam can be changed, it is advantageous if the light beam 6 can also be changed accordingly, which is achieved by appropriate fade-in or adjustment of the light beam 6 to the focus of the X-ray emitter 3 is possible.

Vorteilhaft kann der Lichtsender 5 vier Laserpunktdioden auf­ weisen, die am Umfang des Röntgenbildverstärkers 4 um jeweils 90° zueinander versetzt angeordnet sind. Für jede Laserpunkt­ diode kann ein steuerbares Stellmittel vorgesehen sein, so daß bei veränderbarem Abstand zwischen Röntgenstrahler 3 und Röntgenbildverstärker 4 oder bei verändertem Röntgenstrahlen­ bündel ein entsprechendes Lichtbündel 6 erzeugt wird.The light transmitter 5 can advantageously have four laser point diodes, which are arranged on the circumference of the X-ray image intensifier 4 in each case offset by 90 ° to one another. A controllable adjusting means can be provided for each laser point diode, so that a corresponding light beam 6 is generated when the distance between the X-ray emitter 3 and the X-ray image intensifier 4 or when the X-ray beam changes.

Die Erfindung ist nicht auf ein fahrbares Röntgendiagnostik­ gerät beschränkt und auch nicht darauf, daß der Röntgenstrah­ ler 3 und der Röntgenbildverstärker 4 an einem C-Bogen gela­ gert sind. Die Erfindung kann insbesondere bei Röntgendurch­ leuchtungsanlagen vorteilhaft Anwendung finden.The invention is not limited to a mobile X-ray diagnostic device and also not that the X-ray beam 3 and the X-ray image intensifier 4 are mounted on a C-arm. The invention can be used advantageously in particular in X-ray lighting systems.
