In a method for the presentation of projection images or tomograms from 3D
volume data of an examination volume, particularly from MR or CT volume
data, a grayscale image of a prescribable projection or of a prescribable
section that is composed of individual pixels is calculated from the 3D
volume data. The distance of a voxel or partial volume of the examination
volume represented by the pixel from a reference plane is determined for
each pixel of the grayscale image, and a chromatic value corresponding to
this distance is allocated to each pixel of the grayscale image, the
chromatic value is obtained by color coding of the distance, and a
projection image or tomogram is presented by overlaying or coloring the
grayscale image with the chromatic values allocated to each pixel. The
presentation of a projection image with an unambiguous and immediately
understandable depth, information is thereby enabled.
