Method and apparatus for processing a series of medical x-ray based image recordings

A method for processing a series of medical X-ray based image recordings recorded from a patient, after an administration of contrast agent, in intervals during an inflow of the contrast agent, the method comprising:

• providing the series of medical X-ray based image recordings;
• selecting a series of successive relevant images from the medical X-ray based image recordings;
• examining image elements of the successive relevant images for a maximum image value, wherein when an image element is examined, a value of the image element is considered at a same image coordinate in all relevant images, and an image in which a value of the image element is at a maximum is identified as a maximum image for the image element;
• defining an initial image from the successive relevant images;
• generating a final image in which image elements for which the maximum image is the initial image are represented in a different color from at least one of the image elements for which the maximum image is a different relevant image recorded after the initial image, or the image elements having image values that lie within a specified range of variation in all relevant images;
• and
• outputting the final image.
