The reconstruction of the patient-specific 3D anatomy is a crucial step in the computer-aided preoperative planning based on plain X-ray images. We propose the robust and fast reconstruction method based on fitting the statistical shape and intensity model of a femoral bone into the set of two calibrated X-ray images. We formulate the registration as a non-linear least squares problem, allowing involvement of Levenberg-Marquardt optimisation. The proposed method has been evaluated on a set of 96 virtual X-ray images. The reconstruction accuracy was evaluated using the symetric Hausdorff distance between reconstructed and ground-truth bones and reached 1.28+-1.68 mm on average.
