First Claim
Patent Images
1. A method for classifying tissue density of a breast, comprising:
- accessing mammography image data of the breast;
segmenting the mammography image to identify a breast tissue region representing the breast tissue;
identifying a plurality of regions of interest within the breast tissue region for obtaining image features therefrom;
computing a plurality of image features from the identified plurality of regions of interest; and
classifying the tissue density of the breast using the computed plurality of image features,wherein the step of identifying a plurality of regions comprises;
extracting a contour of the breast tissue region;
generating a plurality of contour segments substantially parallel to the breast tissue region contour and inside the breast tissue region; and
defining a plurality of regions along the generated plurality of contour segments.

Abstract
A method for classifying tissue density of a breast includes obtaining mammography image data and segmenting the mammography image to identify the region representing the breast tissue. A plurality of regions within the breast tissue region are identified for obtaining image features therefrom. A plurality of image features are computed from the identified plurality of regions. The breast tissue density is classified using the computed plurality of image features.
