The present invention relates to an apparatus for displaying medical image data of a body part. It is described to provide (12) medical data of a body part, and subsets of medical image data from the medical data are determined (14). A plurality of measures of information content for the subsets of medical image data is determined (16), wherein a measure of information content is associated with a subset of medical image data. A plurality of weighting factors for the subsets of medical image data is determined (18), wherein a weighting factor is associated with a subset of medical image data and the weighting factor is determined as a function of the measure of information content for that subset of medical image data. Data representative of the subsets of medical image data is output (22) as a function of the plurality of weighting factors.
