Description
Gegenstand des Patentes 930 o6i ist ein Gerät zur Anfertigung von Röntgenaufnahmen des Schädels, bei welchem der von - einem Stativ getragene Kassettenrahmen kreuzgelenkartig gelagert ist. The subject of patent 930 o6i is a device for the production of X-rays of the skull showing the cassette frame carried by a tripod Is mounted like a universal joint.
Aufgabe der Erfindung ist es nun, dieses Gerät dahin weiterauszubilden, daß VergröBerungsaufnahmen der Schädelteile möglich sind. The object of the invention is now to further develop this device that enlargement recordings of the skull parts are possible.
Dies wird erfindungsgemäß dadurch- erreicht, daß der Stativfuß mit einem Ausschnitt für ungehinderten Durchtritt des Röntgenstrahlenbündels versehen ist und daß an dem Kassettenrahmen im Abstand der gewünschten Vergrößerung eine zweite, parallel zu diesem liegende Kassette aufgehängt ist. This is achieved according to the invention in that the stand foot with provided a cutout for unhindered passage of the X-ray beam is and that on the cassette frame at the distance of the desired magnification a second, parallel to this lying cassette is suspended.
Nimmt man beispielsweise den Abstand der Röntgenröhre bis zum oberen Kassettenrahmen mit 20 cm und den Abstand der angehängten zweiten darunter befindlichen Kassette ebenfalls mit 20 cm, so ergibt sich eine Vergrößerung von 1 :2. Dabei sollen die Mittelpunkte der zweiten Kassette, des oberen Kassettenrahmens und der Röntgenröhrenfokus in einer Linie liegen. Die Aufhängung der zweiten Kassette kann in einfacher Weise mittels vier gleichlanger Drähte erfolgen. Selbstverständlich können auch andere Vergrößerungen erzielt werden, je nachdem der Abstand der aufgehängten zweiten Kassette zum oberen Kassettenrahmen bzw. zur Röntgenröhre gewählt wird.Take, for example, the distance between the X-ray tube and the upper one Cassette frame with 20 cm and the distance of the attached second below Cassette also with 20 cm, this results in a magnification of 1: 2. This should the centers of the second cassette, the upper cassette frame, and the x-ray tube focus lie in a line. The suspension of the second cassette can be done in a simple manner by means of four wires of the same length. Of course, others can too Enlargements can be achieved depending on the distance of the suspended second cassette is selected for the upper cassette frame or the X-ray tube.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht. Hierbei sind nicht alle Einzelheiten des Gerätes, wie es schon Gegenstand des Hauptpatentes ist, gezeigt. The subject matter of the invention is illustrated, for example, in the drawing. Not all details of the device are here, as it is the subject of the main patent is shown.
An der Säule 3 des Stativfußes I ist um eine zur Zeiehenebene senkrechte Achse, die Gabel 6 schwenkbar. In der Gabel 6 ist der Kassettenrahmen :ro mit dem kreisrunden Ausschnitt I3 um die Achse I2 drehbar gelagert, die waagerecht in der Zeichenebene liegt. On the column 3 of the stand base I is about a perpendicular to the drawing plane Axis, the fork 6 can be pivoted. In the fork 6 is the cassette frame: ro with the circular cutout I3 rotatably mounted about the axis I2, the horizontally in the Drawing plane lies.
Unten an dem Kassettenrahmen IO sind an den Ecken vier gleichlange Drähte 20 angeordnet, welche einen Rahmen 21 tragen, in welchem ein weiterer Kassettenrahmen 22 mit einer kreisrunden Öffnung 23 ruht. Der Abstand der Röntgenröhre zum oberen Kassettenrahmen und der Abstand des unteren Kassettenrahmens zum oberen Kassettenrahmen ist im Ausführungsbeispiel gleich, so daß hierdurch eine Vergrößerung von 1 2 erzielt wird. Infolge der parallelen Aufhängung des unteren Kassettenrahmens folgt dieser allen Winkellagen des oberen Kassettenrahmens. At the bottom of the cassette frame IO there are four of the same length at the corners Arranged wires 20, which carry a frame 21 in which a further cassette frame 22 with a circular opening 23 rests. The distance from the X-ray tube to the upper one Cassette frame and the distance between the lower cassette frame and the upper cassette frame is the same in the exemplary embodiment, so that a magnification of 1 2 is achieved as a result will. As a result of the parallel suspension of the lower cassette frame, this follows all angular positions of the upper cassette frame.
