3D Reconstruction of Coronary Arterial Tree

The paper describes 3D reconstruction of coronary arterial tree based on two single plane coronary angiograms.Two methods of calculating 3D point are proposed: the least square solution of 3D point based on the theory of perspective projection and the the geometric solution which minimizes the distance to both projective lines.The objective functions of these two methods are compared.The two measures of the reconstruction error, 3D error and 2D error, are defined.The methods are applied to reconstructing 3D coronary arterial tree from two single-plane angiograms,and are validated by the error statistic.
