A three-dimensional (3D) representation of the linear structures in a breast has been constructed by utilising information of the ridges in the craniocaudal (CC) and the mediolateral oblique (MLO) mammographic views of the breast. Blood vessels and ducts appear as ridges in the mammogram. The position and shape of the ridges in the breast are an indicator of malignancy. In the first stage of the proposed 3D reconstruction problem, an algorithm has been developed to find out which linear structure in the CC view and a linear structure in the MLO view correspond to the same 3D structure in the breast. The 3D view of the linear structures is constructed from the abovementioned correspondences. The positional error (per unit length of the reconstructed linear structure) between the manual reconstruction and the algorithmic reconstruction of a linear structure turns out to be better by 20% than a competing approach.
