Procedural guidance using high-resolution, three-dimensional (3D) myocardial scar mapping may offer assistance in directing catheter ablation therapy aimed at eliminating re-entrant arrhythmic pathways. For the purpose of pre-procedural planning and intra-procedural guidance, determining the spatial relationship between myocardial scar, cardiac chambers and vascular structures is a crucial step towards...
An intra prediction (IP) scheme based on 2D geometrical manipulation, called 2DIP, was proposed in to improve the line-based intra prediction (LIP) in H.264/AVC. In this work, we propose ways to reduce the complexity and enhance the efficiency of 2DIP and call the resultant scheme 2D enhanced intra prediction (2DEIP). These enhancements are achieved via block classification and translation vector...
Real-time display of dynamic three-dimensional (3D) cardiac images has important applications in minimally invasive image-guided cardiac surgery and therapy. However, in practice, the high computational cost usually prohibits its application in a real-time medical environment, or else the low image quality does not satisfy the clinical requirements. Surface based organ models or orthogonal image planes...
