Abstract
Digital breast tomosynthesis represents an enhanced type of mammogram for detecting breast cancer. In this disclosure, data from digital breast tomosynthesis is reconstructed into a volumetric database with each voxel having a (x, y, z) coordinate and viewed in true 3D using geo-registered head display unit and geo-registered tools for overall enhanced diagnosis. The breast is imaged under various configurations and the internal architecture of an anatomic feature three-dimensionally analyzed.
