ABSTRACT:
The apparatus contains a detector for detecting radiation emitted from an object under examination, and a device associated therewith for forming an imaging signal. The imaging signal is composed of a sequence of individual image signals each of which represents an individual radiation image of the object under examination. The imaging signal comprises a first individual image signal and second individual image signals following the first individual image signal. The apparatus also contains a signal processing circuit for processing the imaging signal and for forming a display signal thereof, and a display device for receiving the display signal and for displaying a sequence of images of the object under examination. In particular, the signal processing device basically contains three functional elements, that is a storage device, a subtractor, and an evaluation circuit. The storage device is provided for storing the first individual image signal, thereby forming a reference image signal. The subtractor subtracts the reference image signal from each of the second individual image signals. Thereby it forms a difference imaging signal composed of a sequence of individual difference image signals. The monitoring device receives the difference imaging signal. It determines whether a portion of each of the second individual image signals is different from the reference image signal. If so, it issues a change-of-image signal which is indicative of a change of image intensity distribution. In X-ray examinations of a patient, for instance, where a contrast medium is applied to the patient, such change may be caused by the appearance of the contrast medium in the radiation image.
