A method for computer-aided detection of microcalcification clusters using
a digital computer obtains digital mammography data for a single view
image and normalizes and filters the image data to reduce noise. A first
mask is generated and applied to the image data for defining the breast
structure, forming a first cropped image. A second mask is generated and
applied to the image data for defining muscle structure, forming a second
cropped image. An artifact mask corresponding to vascular calcifications
and known imaging artifacts is generated and applied to the first and
second cropped images, defining first and second artifact-masked cropped
images. In a repeated sequence, portions of each artifact-masked cropped
image are processed using an enhancement algorithm and reducing edge
effects to obtain a set of microcalcification cluster candidates and
suspected microcalcification clusters. Image processing algorithms remove
false positives from the listing of microcalcification clusters and
classify candidate microcalcification clusters to identify true
positives.
