ABSTRACT:
An exemplary embodiment comprises a spot film device, a transport mechanism for the transport of an image layer carrier from a ready position into an exposure position and back, and a speed control for the drive motor. A certain time interval which is essentially caused by the transport operations always lies between triggering an X-ray exposure and the actual exposure of the image layer. In order to facilitate release of the X-ray exposure at the proper point in time, the disclosure provides that the overall transport time of the image layer carrier from the ready position into the exposure position is kept constant independently of the mass to be transported. Additionally, the transport time can also be kept constant independently of the different length of the transport path given sequencing of a sub-division program. An inventive X-ray examination device is particularly suited for employment in X-ray diagnostics.
