Nach Fig. 1 werden als Strahlungsquellen dienende Einzelröntgenröhren 1, z.B. Stehanodenröhren, einer Mehrfachstrahlungsquelle, die in einem mit Öl 2 gefüllten strahlensicheren Tank 3 nach bestimmten Verteilungen angeordnet sind, mit einem Generator 4 und einer Steuereinheit 5 "betrieben. Die durch die Fenster 6 emittierten Strahlen 7, die durch die Blenden 8 begrenzt werden, durchstrahlen das zu untersuchende Objekt 8 und erzeugen auf dem Detektor 10 ein kodiertes Bild 11.According to FIG. 1, individual X-ray tubes are used as radiation sources 1, e.g. standing anode tubes, a multiple radiation source, which are arranged according to specific distributions in a radiation-proof tank 3 filled with oil 2, with a generator 4 and a control unit 5 ″. The beams 7 emitted through the windows 6, which are limited by the diaphragms 8, Shine through the object 8 to be examined and generate a coded image 11 on the detector 10.

Nach Fig. 2 werden zwei zueinander kohärente Mehrfachstrahlungsquellen 12 und 13, bestehend aus den Teilen 2, 3, 6 und 8 (siehe Fig. 1), über eine Schaltereinrichtung 14, einen Generator 15 durch eine Steuereinheit 16 nacheinander in kurzem zeitlichen Abstand geschaltet. Die beiden Mehrfachstrahlungsquellen können auch getrennte Generatoren haben.According to FIG. 2, there are two mutually coherent multiple radiation sources 12 and 13, consisting of parts 2, 3, 6 and 8 (see Fig. 1), via a switch device 14, a generator 15 switched by a control unit 16 one after the other at a short time interval. The two multiple radiation sources can also have separate generators.

Fig. 3 zeigt nochmals einen vereinfachten Aufnahmeaufbau, bestehend aus der Mehrfachstrahlungsquelle 17, dem zu durchstrahlenden Objekt 18 und der Detektorfläche 19. Für sogenannte Schrägschnitte kann die Mehrfachstrahlungsquelle und die Detektorfläche um das Objekt 18 beliebig gekippt werden (gestrichelt 20; 21).Fig. 3 shows again a simplified recording structure, consisting from the multiple radiation source 17, the object 18 to be irradiated and the detector surface 19. For so-called The multiple radiation source and the detector surface can be tilted around the object 18 as required (dashed lines) 20; 21).

Das Blitzen der Mehrfachstrahlungsquelle kann kinematographisch erfolgen, um Bewegungsabläufe darstellen zu können. Die Mehrfachstrahlungsquelle kann jedoch auch kontinuierlich betrieben werden, um eine Durchleuchtung des Objektes zu erhalten. Die Brenn-The flashing of the multiple radiation source can take place cinematographically in order to be able to represent motion sequences. The multiple radiation source however, it can also be operated continuously in order to obtain a fluoroscopy of the object. The burning
