According to the present invention, at least one image pair, consisting of a fluoroscopic image and an angiographic image taken from the same viewing position of the imaging device relative to the patient at the time of capturing the respective image, is acquired. This is referred to as the acquisition phase. This is followed by a live phase, in which a live fluoroscopic image is registered individually with the fluoroscopic image of at least one image pair, such that the spatial relationship between the live fluoroscopic image and the fluoroscopic image, and thus with the angiographic image and the image pair in general, becomes known.
