Abstract
Description
Bei bekannten Röntgendiagnostikanlagen werden Röntgenbilder mit Hilfe unterschiedlicher bildgebender Systeme angefertigt. So ist es z. B. bekannt, ein Röntgengerät zur Anfertigung von Röntgenfilmaufnahmen und Durchleuchtungsbildern mit Hilfe einer Bildverstärker-Fernsehkette auszurüsten. Der Fernseh kette kann dabei eine Einrichtung zur Digitalisierung und An fertigung von Subtraktionsbildern zugeordnet sein. Für ver schiedene Betriebsarten sind also unterschiedliche bildge bende Systeme vorhanden.In known X-ray diagnostic systems, X-ray images are used made with the help of different imaging systems. So it is z. B. known an X-ray machine for the production of X-ray film and fluoroscopic images with the help to equip an image intensifier television chain. The television chain can be a facility for digitization and connection production of subtraction images. For ver Different operating modes are therefore different images systems exist.
Der Erfindung liegt die Aufgabe zugrunde, eine Röntgendia gnostikanlage so auszubilden, daß für unterschiedliche Be triebsarten, wie Röntgen-Subtraktionstechnik, Durchleuch tungsbilder mit niedriger Dosisleistung und Röntgenaufnahmen mit hoher Dosisleistung, nur ein einziges Bildaufnahmesystem erforderlich ist.The invention has for its object an X-ray slide training the gnostic system so that for different loading modes, such as X-ray subtraction technology, fluoroscopy with low dose rate and X-rays with high dose rate, only a single image acquisition system is required.
Diese Aufgabe ist erfindungsgemäß gelöst durch die Merkmale des Patentanspruchs 1. Die Erfindung geht davon aus, daß mit einem digitalen Flachdetektor, z. B. auf der Basis von a: Si, die erforderlichen unterschiedlichen Bildverarbeitungstechni ken realisiert werden können.According to the invention, this object is achieved by the features of claim 1. The invention assumes that with a digital flat panel detector, e.g. B. based on a: Si, the required different image processing technologies ken can be realized.
Weiterbildungen der Erfindung ergeben sich aus den Unteran sprüchen.Further developments of the invention result from the Unteran sayings.
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 eine Patientenliege 1 dargestellt, auf der ein Patient 2 liegt, der von der von einem Röntgenstrah ler 3 ausgehenden Röntgenstrahlung durchstrahlt wird. Die Röntgenstrahlung trifft auf einem Flachdetektor 4 auf, der z. B. aus einer Matrix von Detektorelementen auf der Basis von amorphem Silicium gebildet ist. Die Ausgangssignale des Flachdetektors 4 werden einer Bildverarbeitungseinheit 5 zu geführt, der mehrere weitere Bildverarbeitungseinheiten 6, 7, 8 nachgeschaltet sind. Die von den Bildverarbeitungseinheiten 6, 7, 8 erzeugten Röntgenbilder werden auf Monitoren 9, 10, 11 wiedergegeben. Die Bildverarbeitungseinheit 6 kann z. B. übliche Durchleuchtungsbilder mit geringer Strahlendosislei stung erzeugen, während die Bildverarbeitungseinheit 7 Rönt genaufnahmen mit hoher Auflösung bei hoher Dosisleistung er zeugen kann. Die Bildverarbeitungseinheit 8 kann zur Erzeu gung von digitalen Subtraktionsbildern ausgebildet sein, in dem in ihr zwei unterschiedliche Bilder des Patienten 2 von einander subtrahiert werden und das Subtraktionsbild auf dem Monitor 11 wiedergegeben wird.In the drawing, a patient couch 1 is shown on which a patient 2 lies, who is irradiated by the X-ray radiation emanating from an X-ray beam 3 . The X-ray radiation strikes a flat detector 4 which, for. B. is formed from a matrix of detector elements based on amorphous silicon. The output signals of the flat detector 4 are fed to an image processing unit 5 which is followed by a number of further image processing units 6 , 7 , 8 . The x-ray images generated by the image processing units 6 , 7 , 8 are reproduced on monitors 9 , 10 , 11 . The image processing unit 6 can e.g. B. generate conventional fluoroscopic images with a low radiation dose, while the image processing unit 7 X-ray recordings with high resolution at a high dose rate he can testify. The image processing unit 8 can be designed to generate digital subtraction images, in which two different images of the patient 2 are subtracted from one another and the subtraction image is displayed on the monitor 11 .
Anstelle von drei individuellen Monitoren 9, 10, 11 kann auch ein einziger Monitor 12 vorgesehen sein, auf dem wahlweise die von den Bildverarbeitungseinheiten 6, 7, 8 erzeugten Röntgenbilder wiedergegeben werden.Instead of three individual monitors 9 , 10 , 11 , a single monitor 12 can also be provided, on which the x-ray images generated by the image processing units 6 , 7 , 8 are optionally displayed.
Der Flachdetektor 4 kann Röntgenaufnahmen, die mit der Fil maufnahme vergleichbar sind, als auch Durchleuchtungsbilder entsprechend der Indirekttechnik mit einer Bildverstärker- Fernsehkette erzeugen. Die Bilddaten des Flachdetektors 4 werden digital ausgelesen und eignen sich damit auch in der geschilderten Weise für die digitale Subtraktionsangiogra phie.The flat detector 4 can generate X-ray images that are comparable to the film, as well as fluoroscopy images according to the indirect technology with an image intensifier television chain. The image data of the flat detector 4 are read digitally and are therefore also suitable in the manner described for digital subtraction angiography.
Das bei herkömmlichen Röntgendiagnostikanlagen übliche Ziel gerät zur Aufnahme von Filmkassetten oder alternativ dazu vorgesehene Magazineinrichtungen, die Bildverstärker-Fern sehkette und die dieser nachgeschaltete Digitalisierungsein richtung entfallen und werden durch den Flachdetektor 4 er setzt. The conventional target in conventional X-ray diagnostic equipment for recording film cassettes or alternatively provided magazine devices, the image intensifier television chain and the digitization device connected downstream are omitted and are set by the flat detector 4 .
Die Zuordnung des Röntgenstrahlers 3 zum Flachdetektor 4 kann in bekannter Weise durch einen C-Bogen, durch einen U-Bügel oder sonstige bekannte mechanische Verbindungen erfolgen, wie dies durch die strichpunktierte Linie 13 schematisch darge stellt ist. Es kann aber auch eine rechnergesteuerte Zuord nung vorgesehen sein.The assignment of the X-ray emitter 3 to the flat detector 4 can be carried out in a known manner by a C-arm, by a U-bracket or other known mechanical connections, as is shown schematically by the dash-dotted line 13. However, a computer-controlled assignment can also be provided.
Die Erfindung schafft eine universelle radiologische Röntgen diagnostikanlage mit einheitlicher Abbildungsgeometrie für alle Betriebstechniken.The invention creates a universal radiological x-ray diagnostic system with uniform imaging geometry for all operating techniques.
