1. A method for visualizing deposits in blood vessels, comprising: reconstructing the 2D slice images from measurement data for a sequence of 2D slice images of the blood vessels, with image data of the 2D slice images being post-processed for local determination of at least one of brightness values and default values on which these are based in the 2D slice images; and marking one or more image areas, in presentation of the 2D slice images, by positioning a marking element which is interactively shiftable in the 2D slice images and around which a predeterminable marking area is defined; and automatically color-coding and presenting pixels of the image areas, in the post-processing, according to a predeterminable transfer function which assigns different colors to different value ranges of at least one of brightness values and default values on which the brightness values are based.
