Cardiac Motion Estimation with Coronary Angiographic Image Sequences

Abstract:

An approach for estimating cardiac dynamics with X-ray coronary artery angiographic image sequences covering one or several cardiac cycles is proposed. According to a priori knowledge about cardiac anatomy and dynamics, complex cardiac dynamic performances are decomposed into global rigid motion, global deformation and local motion and deformation. Parameters of all components are quantitatively estimated in a manner of global-to-local and coarse-to-fine to obtain quantitative description of cardiac motion. Experimental results with clinical data demonstrated the validity.
