Patent ID: 8805049

Claim:
A method for computer-aided detection (CAD) of anatomical abnormalities in x-ray mammograms based on a foundational CAD processing algorithm, the foundational CAD processing algorithm being characterized by at least one of non-shift-invariance, non-rotational-invariance, and non-inversional-invariance, the method comprising: receiving a first x-ray mammogram image of a breast in digital form; processing by digital computer the first x-ray mammogram image to generate at least one altered version thereof that differs therefrom by at least one of image shift, image rotation, and image inversion; individually processing the first x-ray mammogram image and each of the at least one altered versions using the foundational CAD algorithm to generate a respective plurality of individual CAD detection sets; and comparing the plurality of CAD detection sets to generate an overall CAD detection set for the first x-ray mammogram image, wherein the foundational CAD algorithm is non-deformation-invariant in at least one direction.
