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. From German Utility Model 88 06 671 is an X-ray diagnostic apparatus with each other to a bracket gegenüberlie quietly arranged X-ray source and X-ray image intensifier known. Am Röntgenbildverstärker ist als Positionierhilfe ein Lichtsender zum Kennzeichnen des Zentralstrahlbereiches eines vom Röntgenstrahler ausgesandten Röntgenstrahlenbündels vorgesehen. At the X-ray image intensifier, a light transmitter for designating the range of a central beam emitted by the X-ray source X-ray beam is provided as a positioning aid. Als Lichtsender können ein erster und ein zweiter um 90° zueinanderversetzte Lichtsender vorgesehen sein, die jeweils einen Fächerstrahl aussenden. The light transmitter may be a first and a second may be provided by 90 ° offset from each other light transmitters, each of which emit a fan beam. Die Lichtfächer kreuzen sich hierbei im Zentralstrahl des Röntgenstrahlenbündels. The fan of light cross each other here in the central ray of the x-ray beam. Es ist bekannt, den Lichtsender als Laserlichtquelle auszufüh ren. It is known auszufüh the light emitter as a laser light source reindeer.

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 to perform a Röntgendiagnostikeinrich tung with a positioning aid in such a way that a positioning of the X-ray source and X-ray image intensifier with respect to an object under examination is possible without this X-radiation is required.

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

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. The advantage of the invention is that senders particular tion, by providing the light at the X-ray image intensifier with a Posi at which the X-ray image intensifier tersuchungstisch is over a Un, now a light beam is directed to the object under examination, which corresponds to a source-emitted by the X-ray beam. Das durchleuchtete Feld wird durch Projektion des Lichtbündels auf das Objekt nunmehr sichtbar, so daß eine Positionierung ohne Röntgenstrahlung erfolgen kann. The by illuminated field is now visible through the projection of the light beam to the object, so that a positioning without X-ray radiation can take place.

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 will become apparent from the following description of Ausführungsbeispie les reference to the drawings in conjunction with the Unteransprü 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. The X-ray diagnostic apparatus 1 shown in the figure is carried out at play as a mobile X-ray diagnostic device and has an X-ray source 3 and a Röntgenbildver more 4 which are arranged at the ends of a C-arm 2 opposite to each other. Gemäß der Erfindung ist am Röntgenbildverstärker 4 ein Lichtsender 5 vorgesehen, dessen Lichtbündel 6 auf den Röntgenstrahler 3 fokussiert ist. According to the invention, a light transmitter 5 is provided on the X-ray image intensifier 4, the light beam is focused on the X-ray source 3. 6 Vor zugsweise ist hierbei das Lichtbündel 6 so eingeblendet, daß es einem vom Röntgenstrahler 3 ausgehenden Röntgenstrahlen bündel entspricht. Before preferably, the light beam 6 is in this case so displayed as to correspond to one extending from the X-ray source 3 X-ray beam. Bei fest vorgegebenen Abstand zwischen Röntgenstrahler 3 und Röntgenbildverstärker 4 , ist eine ein malige Justierung des Lichtsenders 5 ausreichend. At fixed predetermined distance between the X-ray tube 3 and X-ray image intensifier 4, a one-off adjustment of the light transmitter 5 is sufficient. 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. However, the distance between the X-ray source 3 and the X-ray image intensifier 4 or the opening angle of the X-rays are bundle changed, so it is convenient, although the light beam 6 can be changed according to what the by appropriate display or adjustment of the light beam 6 to the focus X-ray source is possible. 3

Vorteilhaft kann der Lichtsender 5 vier Laserpunktdioden auf weisen, die am Umfang des Röntgenbildverstärkers 4 um jeweils 90° zueinander versetzt angeordnet sind. Advantageously, the light emitter can have 5, four laser spot diodes, which are arranged offset at the periphery of the X-ray image intensifier 4 by 90 ° to each other. 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. For each laser diode point a controllable actuating means can be provided so that bunch at a variable distance between the X-ray tube 3 and X-ray image intensifier 4 or modified X-rays, a corresponding light beam is generated. 6

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. The invention is not device to a mobile X-ray diagnostic limited, nor the fact that the X-Ray ler 3 and the X-ray image intensifier 4 are of a C-arm gela device. Die Erfindung kann insbesondere bei Röntgendurch leuchtungsanlagen vorteilhaft Anwendung finden. In particular, the invention can lighting systems for X-ray through advantageous to apply.
