Abstract: Determining a three-dimensional model of a rim of an anatomical structure using two-dimensional images of the rim. The images are taken from different directions and each image can provide a different two-dimensional contour of the rim. Corresponding pairs of points are identified in the images and are used with a transformation matrix to calculate the three-dimensional model. The model may then be used to assist physicians in implantation procedures.
