Abstract

The invention relates to a method of visualizing a three-dimensional volume image data set (1). A two-dimensional image (15) is then formed by projecting the volume image data on a projection plane in that for each pixel (16) there is determined an intensity value which corresponds to the maximum value or minimum value of the mean intensity along a projection path (17) which extends through the imaged volume and is associated with the relevant pixel. In order to determine the mean intensity, averaging is performed over a plurality of intensity values which neighbor one another along the projection path (17). In order to achieve effective noise suppression as well as adequate image contrast, averaging is performed over at least partly overlapping intervals (18 to 22) along the projection path (17). The method in accordance with the invention offers the advantage that the user can choose the width of the averaging interval as an additional free parameter, so that image contrast and background noise can be influenced independently from one another to a significant extent.
