Abstract :
This paper presents a two stages method for three-dimensional (3-D) coronary artery motion estimation from rotational X-ray projection. In the first step we estimate a 3-D skeleton of the coronary tree at each cardiac phase, using a deformable coronary tree model. The second stage proceeds with a motion estimation between the 3-D reconstructed coronary trees over the cardiac cycle. This estimation is based on a 3-D B-spline interpolation model.
