A method for computing a color-coded analysis image of an examination area of an examination object from a temporal sequence of fluoroscopic images of the examination area comprising a vascular system containing arteries and/or veins is provided. An acquisition time instant has been assigned to each of the fluoroscopic images representing a given distribution of a material embolizing some of the vascular system. The fluoroscopic image spatially corresponds to an analysis image pixel by pixel. A computer receives the fluoroscopic images with a color attribute assigned to each pixel of the analysis image at an image point and a time instant. If a pixel differs from a pixel at a preceding time instant, the color attribute assumes a color attribute of the time instant and the difference. If a pixel corresponds to a background color of the analysis image, the color attribute assumes a background color.
