Abstract

In an embodiment of the invention, a plurality of images of a region under examination are recorded at different times. Anatomical information and flow information are derived from the images. The anatomical information may relate to the course of vessels or the structure of perfused tissue. The temporal component of the flow information can advantageously be combined with the anatomical information in a resultant image. An intensity-dependent fenestration assigns a gray-scale value to pixels of the resultant image in accordance with the anatomical information. A time-dependent fenestration assigns a chromaticity to the pixels of the resultant image in accordance with the flow information and the gray-scale values and the chromaticities are assigned independently of one another. Intensity-dependent fenestration is combined with time-dependent fenestration so that chromaticities and gray-scale values are independent of one another and the anatomical information and the flow information are depicted undistorted in the resultant image.
