Abstract: The image processing unit (5) has an input for the image signal (8) from the X-ray apparatus and an input for a signal (9) indicating the movement phase of the imaged body volume of the patient (2), a memory storing previous images for the body and the corresponding movement phases, with determination and display of the spacing between the movement phases for the actual image and the immediately preceding image of the body volume. An Independent claim for a method for correlation of an actual image of a body volume with a preceding image for a different movement phase is also included.

Abstract: The invention relates to a device and to a method for combining two images, especially for superimposition of static vascular maps (B), which were taken at different phases of the cardiac cycle and/or the respiratory cycle and were archived in a memory (6), on a current image (A) of a catheter (2, 8) in the vascular system (9). In the method, a defined section of a map image (B) around the estimated actual position of the catheter is selected and is displayed superimposed on the current image (A) in an image (C) on a monitor (10). The map image (B) used for this is preferably selected by means of an electrocardiogram to match the particular cardiac cycle. The position of the catheter relative to the map image (B) can be estimated using a distance image (D).

Abstract: The invention relates to the association of a current (X-ray image) image of a body volume with one of several stored previous images, the ECG and the respiratory cycle being determined each time together with the images. Using this data, that one of the previous images is chosen which is closest to the current image in respect of cardiac rhythm and respiratory cycle. The resultant association yields a very high accuracy enabling superposed reproduction of the current image and the associated previous image.
