.Reconstruction of three-dimensional coronary arterial dynamics from multi-view angiogram sequences[J].Optoelectronics Letters,2006,2(1):68-71 Reconstruction of three-dimensional coronary arterial dynamics from multi-view angiogram sequences SUN Zheng YU Dao-yin School of Precision Instrument and Optoelectronic Engineering, Tianjin University, Key Laboratory of Opto-electronics Information and Technical Science ( Tianjin University) , EMC, Tianjin 300072, China Abstract:       A method for reconstructing 3-D motion of coronary arteries from single-plane X-ray angiogram sequences on two approximately orthogonal views is proposed. 2-D motion is firstly estimated separately along vascular centerlines extracted from angiographic projection pairs. The 3-D displacement vector of each arterial skeleton point at one instant is then reconstructed by calculating the spatial coordinates of its two ends from corresponding projections. 3-D configuration and dynamics of arteries are finally characterized. The effectiveness of the algorithm has been demonstrated on vascular phantom images and clinical angiograms and results are encouraqing.
