Abstract:
1. A method for using computer-aided diagnosis (CAD) for digital tomosynthesis mammograms (DTM) comprising using a processor for: retrieving a DTM image file having a plurality of DTM image slices; applying a three-dimensional analysis to the DTM image file to detect lesion candidates defining a location; identifying a volume of interest and locating its center at the location, which is one of high gradient convergence or high response; segmenting an object corresponding to the volume of interest by a three dimensional method; extracting one or more object characteristics from the object corresponding to the volume of interest, the object characteristics being one of a morphological feature, a gray level feature, or a texture feature; and invoking a classifier to determine if the object corresponding to the volume of interest is a breast lesion or normal breast tissue.
