A method of analysing breast tissue from an image comprising determining a reference value from a reference spot 1070 in the image, establishing an h int representation of the image, and using the hintrepresentation in analysis of the tissue to quantify the breast and compute a calibration error k. A system runs an inner breast edge 1040 detection algorithm (1310 fig. 13) on the electronic image to detect the inner breast edge on the image (1315), and refines the inner breast edge location (1340) if a calibration error k is not acceptable (1324). Also disclosed is automatic estimation of breast composition and temporal analysis of images. The inner breast edge may be determined using a histogram of the image and a gap between two peaks of the histogram corresponds to an inner breast edge. |
