Abstract
An exemplary embodiment includes an x-ray image intensifier television chain, an image memory, and a subtraction device which subtracts the stored and the current video signals. A radiographic control device derives control pulses for controlling image storage from the EKG of the patient. A second image memory is connected with the output of the subtraction device. The radiographic control device is connected to both image memories and is designed in such a manner that it triggers the storage at selected different times during a heart cycle.
