The CAD algorithms begin with image enhancement of the digitized mammographic images to
accentuate all areas that could be individual microcalcifications and densities. The microcalcification and
density detectors then identify the areas that are most likely to be individual microcalcifications and
densities, based on an initial analysis of morphological and intensity measurements. The types of

densities detected are depicted in and include spiculated and non-spiculated masses,
architectural distortions, and focal asymmetric densities.

Note:
Focal asymmetric densities are difficult to depict pictorially, but are detected by SecondLook.
