The invention presents a way to automatically assess the quality of acquired (S 1 , S 2 ) digital mammographic images with respect to the image positioning of a patient's breast. The automated digital quality assessment (S 3 ) is executed in real time and preferably notifies (S 4 ) the technologist instantly if the image positioning quality of a mammographic image is inadequate. This makes it possible to retake the image while the patient is still present at the examination facility. The quality assessment notification includes information to the technologist, preferably both visually and statistically of land-mark positioning measurements. Alternatively, the digital quality assessment is accompanied by a computerized decision of whether the mammogram needs to be retaken, requiring a minimum of involvement, if at all, from the technologist. The invention hence provides a set of quality-assured mammographic images that can be stored (S 5 ) and later accessed by a radiologist for review and diagnosis (S 6 ). |
