1. A method for computer-aided detection (CAD) of anatomical abnormalities in x-ray mammograms based on a foundational CAD processing algorithm, said 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 said 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 said first x-ray mammogram image and each of said at least one altered versions using said foundational CAD algorithm to generate a respective plurality of individual CAD detection sets; and comparing said plurality of CAD detection sets to generate an overall CAD detection set for said first x-ray mammogram image.
