Description
Die Erfindung betrifft ein Röntgendiagnostikgerät für mammographische Röntgenaufnahmen mit einem U-förmigen Träger, an dessen freien Enden eine Röntgenröhre und eine Bildaufnahmeeinrichtung befestigt sind und der um eine parallel zu seinen seitlichen Schenkeln und senk recht zu seinem diese Schenkel verbindenden Joch liegen de Achse schwenkbar gelagert ist.The invention relates to an X-ray diagnostic device for mammographic x-rays with a U-shaped Carrier, at the free ends of an X-ray tube and an image recording device are attached and around one parallel to his side legs and lower lie to the right of its yoke connecting these legs de axis is pivotally mounted.
Es ist ein Röntgendiagnostikgerät dieser Art bekannt bei dem die Bildaufnahmeeinrichtung eine Brustauflageplatte aufweist, und bei dem in dem Joch ein Kompressionswagen verstellbar gelagert ist, der eine über der Auflageplatte liegende Kompressionsplatte in Richtung auf die Auflage platte bewegt und das Aufnahmeobjekt komprimiert. Bei ei nem solchen Gerät besteht der Wunsch, Röntgenstereobild paare anzufertigen. Hierzu ist es erforderlich, das Auf nahmeobjekt aus zwei verschiedenen Richtungen zu durch strahlen.An X-ray diagnostic device of this type is known from which the image recording device a breast support plate and in which a compression carriage in the yoke is adjustable, one over the platen lying compression plate in the direction of the support plate moves and the subject is compressed. With egg In such a device, there is a desire for x-ray stereo image to make pairs. For this it is necessary to open the object from two different directions shine.
Der Erfindung liegt die Aufgabe zugrunde, ein Röntgen diagnostikgerät der eingangs genannten Art so auszubil den, daß in einfacher Weise zwei verschiedene Aufnahmen mit zwei verschiedenen Strahlenrichtungen anfertigbar sind.The invention has for its object an x-ray to train diagnostic device of the type mentioned at the beginning that in a simple way two different shots can be produced with two different beam directions are.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Röntgenröhre in Richtung des sie tragenden Schenkels zwi schen zwei Endstellungen verstellbar gelagert ist derart, daß in diesen beiden Endstellungen die beiden Bilder eines Stereobildpaares anfertigbar sind. Bei dem erfindungsgemäßen Röntgendiagnostikgerät genügt es, die Röntgenröhre für die eine Aufnahme eines Stereobild paares in ihre eine und für die zweite Aufnahme in ihre andere Endstellung zu bringen. Die Verstellung in Rich tung des sie tragenden Schenkels ergibt dabei einen sehr einfachen mechanischen Aufbau.This object is achieved in that the X-ray tube in the direction of the thigh carrying it rule two end positions is adjustable so that the two images of a stereo image pair can be made in these two end positions. At the X-ray diagnostic device according to the invention suffices to the x-ray tube for taking a stereo image couple in their one and for the second inclusion in their to bring another end position. The adjustment in Rich tion of the leg carrying it results in a very simple mechanical construction.
Die Erfindung ist nachfolgend anhand eines in der Zeich nung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:The invention is based on a in the drawing voltage illustrated embodiment explained in more detail. Show it:
Fig. 1 ein Röntgendiagnostikgerät für mammographische Röntgenaufnahmen zur Erläuterung des Erfin dungsgedankens, und Fig. 1 is an X-ray diagnostic device for mammographic X-rays to explain the inven tion idea, and
Fig. 2 eine schematische Darstellung der für die Er findung wesentlichen Einzelheiten des Röntgen diagnostikgeräts gemäß Fig. 1. FIG. 2 shows a schematic illustration of the details of the X-ray diagnostic device according to FIG. 1 that are essential for the invention.
In der Fig. 1 sind ein Gehäuse 1 für eine Röntgenröhre und eine Aufnahmeplatte 2 zur Anfertigung üblicher Mammo graphien dargestellt, in die eine Röntgenfilmkassette 2a einschiebbar ist. Das Gehäuse 1 und die Aufnahmeplatte 2 sind über einen Halter 3 miteinander verbunden, der eine horizontale Achse 4 aufweist, mit der er an einem Stativ 5 höhenverstellbar gelagert ist. Die Teile 1, 2, 3 bilden einen U-förmigen Träger, an dessen freien Enden die Rönt genröhre und die Bildaufnahmeeinrichtung befestigt sind und der um die parallel zu seinen seitlichen Schenkeln und senkrecht zu seinem diese Schenkel verbindenden Joch (Halter 3) liegende Achse 4 schwenkbar gelagert ist. Durch Schwenkung des U-förmigen Trägers 1, 2, 3 ist da bei die Durchstrahlungsrichtung festlegbar, unter der Röntgenaufnahmen angefertigt werden. Für die Anfertigung einer Röntgenaufnahme oder eines Stereobildpaares wird die zu untersuchende Brust auf der Auflageplatte 2 ge lagert und mit Hilfe einer Kompressionsplatte 9 kompri miert. Die Kompressionsplatte 9 steckt mit einem Ansatz in einer Öffnung 8 eines Kompressionswagens 6, der in Richtung auf die Auflageplatte 2 und von dieser weg moto risch verstellbar ist. Der Ansatz ist in einem Schlitz 7 des Halters 3 geführt.In Fig. 1, a housing 1 for an X-ray tube and a mounting plate 2 for the preparation of conventional mammo graphics are shown, into which an X-ray film cassette 2 a can be inserted. The housing 1 and the mounting plate 2 are connected to one another via a holder 3 which has a horizontal axis 4 with which it is mounted on a tripod 5 in a height-adjustable manner. The parts 1 , 2 , 3 form a U-shaped carrier, at the free ends of which the X-ray tube and the image recording device are fastened and about the axis 4 lying parallel to its lateral legs and perpendicular to its yoke connecting these legs (holder 3 ) is pivotally mounted. By pivoting the U-shaped support 1 , 2 , 3, it is possible to determine the direction in which the X-rays are taken. For preparing an X-ray image or a stereo image pair the superimposed ge to be examined breast on the platen 2 and Kompri mized with the aid of a compression plate 9 is. The compression plate 9 is inserted with an approach in an opening 8 of a compression carriage 6 , which is adjustable in the direction of the support plate 2 and away from it. The approach is performed in a slot 7 of the holder 3 .
Die Fig. 2 zeigt die zu untersuchende Brust zwischen der Kompressionsplatte 9 und der Auflageplatte 2. Ferner ist in der Fig. 2 der Fokus 10 der Röntgenröhre schematisch dargestellt. Aus der Fig. 2 geht hervor, daß die Rönt genröhre und damit der Fokus 10 in Richtung des sie tra genden Schenkels (Gehäuse 1) des U-förmigen Trägers 1, 2, 3 zwischen zwei Endstellungen I, II verstellbar gelagert ist. In der Seitenansicht gemäß Fig. 2 wird eine Rönt genaufnahme in der Stellung I des Fokus 10 und die zweite Röntgenaufnahme in der Stellung II angefertigt. Auf diese Weise erhält man zwei Bilder eines Stereobildpaares, die anschließend in bekannter Weise betrachtet werden können, so daß der Betrachter einen räumlichen Eindruck des un tersuchten Objektes bekommt. Fig. 2 shows the breast to be examined between the compression plate 9 and the support plate 2. Furthermore, the focus 10 of the X-ray tube is shown schematically in FIG. 2. From Fig. 2 it can be seen that the X-ray tube and thus the focus 10 in the direction of the tra leg (housing 1 ) of the U-shaped carrier 1 , 2 , 3 between two end positions I, II is adjustably mounted. In the side view according to FIG. 2, a radiograph is taken in position I of focus 10 and the second radiograph in position II. In this way you get two images of a stereo image pair, which can then be viewed in a known manner, so that the viewer gets a spatial impression of the un-examined object.
