Method, apparatus, and program for detecting abnormal patterns in a mammogram

摘要

Mammary gland content rates are employed to detect abnormal patterns. A mammary gland content rate r(x, y) is calculated for each pixel of a mammogram P obtained by a radiation imaging apparatus (2). Thereafter, an average value rave of the mammary gland content rates within a breast region MR is calculated, using the mammary gland content rates r (x, y) of each pixel. Abnormal pixels AP that constitute abnormal patterns are detected, employing the mammary gland content rates r(x, y), the average value rave, and a set reference value Rref.
