Purkinje fiber network (PFN), one of the most important components of the ventricular conduction system, is crucial in modeling ventricular tachycardia and fibrillation. Construction of anatomical detail Purkinje fiber network, however, is a very challenging task. In this paper, we present a novel method for restoring the 3D PFN in the left ventricle (LV) by manifold learning. Motivated by the fact...
In this paper, we present an integrated model of 3D human ventricle to simulate the effects of ischemia on wave propagation. To deal with the no-flux boundary conditions, a phase-field method is employed. The major advantage of the method is that it can automatically handle the boundary conditions. Through the increasing of concentration of extracellular K+ and ischemic size, the propagation of spiral...
Volume rendering of 3D anatomical and medical data would be valuable in medical diagnosis and surgical planning. In this paper, we investigated the visualization of the segmented heart obtained by the cross-sectional data from the Visible Human Project, and proposed an accelerated rendering method to speed up the original ray-casting rendering method. To provide a satisfactory visualization quality...
