Hierarchical Region Based Template Matching Technique for Global Motion Reduction of Coronary Cineangiograms

K. A. S. H. Kulathilake, L. Ranathunga, G. R. Constantine, and N. A. Abdullah
Abstract—The Coronary Cineangiogram (CCA) is an invasive medical image modality which is used to determine the stenosis in the Coronary Arteries. The global motion occurring due to the heart beat makes great disturbance to obtain the visual alignment among the vessel structure shown in the CCA frames. Therefore, the recorded vessel structure’s position in CCA varies within the frame sequence. This paper describes a hierarchical region based template matching technique to reconstruct the CCA by reducing the global motion artifacts. This proposed motion reduction technique is efficient and it reconstructs the CCA by reducing the background motion as desired. Experimental results of this method have shown its’ ability to maintain the visual alignment of the internal blood flow among the frames.

Index Terms—Angiography, computer aided diagnosis, image motion analysis, medical diagnostic imaging component.
