Assessing Coronary Arterial Dynamics from Cineangiograms

Abstract:

Assessing displacement fields of coronary arterial skeletons from a pair of nearly orthogonal cineangiographic image sequences is addressed. Projections of vessel skeletons are firstly extracted from each frame. Then, 2D displacement vectors of vessel skeletons during each temporal interval are estimated along the image sequences. 3D displacement vectors of each skeleton point are finally reconstructed along the overall sequences. Possible errors are discussed. Experimental results with clinically acquired in vivo image data have demonstrated the validity of the method.
