Ensemble learning of the atrial fiber orientation with physics-informed neural networks

Eà Magaña, S Pezzuto, FS Costabal - arxiv preprint arxiv:2410.23388, 2024 - arxiv.org
The anisotropic structure of the myocardium is a key determinant of the cardiac function. To
date, there is no imaging modality to assess in-vivo the cardiac fiber structure. We recently …
