We propose FiberNet, a method to estimate in-vivo the cardiac fiber architecture of the
human atria from multiple catheter recordings of the electrical activation. Cardiac fibers play …

Computational models of cardiac electrophysiology have gradually matured during the past
few decades and are now being personalised to provide patient-specific therapy guidance …

The eikonal equation has become an indispensable tool for modeling cardiac electrical
activation accurately and efficiently. In principle, by matching clinically recorded and eikonal …

Generating numerical solutions to the eikonal equation and its many variations has a broad
range of applications in both the natural and computational sciences. Efficient solvers on …

A key mechanism controlling cardiac function is the electrical activation sequence of the
heart's main pumping chambers termed the ventricles. As such, personalization of the …

We present a new graph-based method, called discrete geodesic graph (DGG), to compute
discrete geodesics in a divide-and-conquer manner. Let M be a manifold triangle mesh with …

Electroanatomical mapping, a keystone diagnostic tool in cardiac electrophysiology studies,
can provide high-density maps of the local electric properties of the tissue. It is therefore …

Abstract Fast Iterative Method (FIM), a grid-based ray-tracing algorithm, has a computational
efficiency far exceeding that of conventional fast marching method (FMM) in serial …

The identification of the initial ventricular activation sequence is a critical step for the correct
personalization of patient‐specific cardiac models. In healthy conditions, the Purkinje …

This paper presents a contribution to level‐set reinitialization in the context of discontinuous
Galerkin finite element methods. We focus on high‐order polynomials for the discretization …
