Noninvasive cardiac electrophysiological imaging aims to mathematically reconstruct the spatio-temporal dynamics of cardiac current sources from body-surface electrocardiography data. This ill-posed problem is often regularized by imposing a certain constraining model on the solution. However, it enforces the source distribution to follow a pre-assumed spatial structure that does not always match...
Imaging the bioelectrical source distribution along the infarct border is of important therapeutic potential as infarct border is the common site for reentry circuits leading to life-threatening arrhythmias. Although it can be tackled by computational reconstruction of volumetric cardiac source using body-surface voltage data, the problem is notoriously ill-posed without a unique solution. Progress...
