IMAGING TOMOSYNTHESIS SYSTEM, IN PARTICULAR MAMMOGRAPHY SYSTEM

An imaging tomosynthesis system, in particular a mammography system, includes a computer system which generates x-ray projections of an examination object from a plurality of projection angles. The system further reconstructs a stack of tomosynthetic slice images, generates at least one overview image of density values of an examination object from the tomosynthetic image data, selects characteristic density values in the stack at at least one plane position, and determines the geometric level of the at least one selected characteristic density value. The overview image is then displayed with a color value correlated to the geometric level of the at least one characteristic density value.
