Dong Ping Zhang, Xiahai Zhuang, Sebastien Ourselin, Daniel Rueckert, Benoit M. Dawant, David R. Haynor
2011 Medical Imaging 2011: Image Processing  
In this paper, we present a novel approach for simultaneous motion tracking of left ventricle and coronary arteries from cardiac Computed Tomography Angiography (CTA) images.  ...  The vessel centrelines are then extracted as the minimal cost path from the enhanced images. The centrelines at end-diastolic (ED) are used as prior input for the motion tracking.  ...  In this paper, we propose an atlas-based segmentation method and registration-based motion tracking framework to achieve this.  ...
