Abstract
A method and apparatus for reconstructing an image of an organ or body part from at least two images of the organ or body part taken using radiography in two positions of the organ or body part separated by a rolling movement of the organ or body part. The rolling movement of the organ or body part is determined between two positions, extracting motion vectors for the surface of the organ or body part, interpolating motion vectors between the motion vectors extracted, and reconstructing an image of the organ or body part. The method and apparatus allows the three-dimensional structure of the tissue to be reconstructed while reducing ambiguities due to the presence of a lesion overlaying the tissue.
