Fast Myocardial Wall Thickness Estimation Using Morphological Sphere Propagation for Ventricular Tachycardia Substrate Detection
Accurate left ventricular (LV) wall thickness (WT) estimation can identify arrhythmogenic ventricular tachycardia (VT) channels, but Laplace-based method is limited by computational inefficiency. This study proposes the Morphological Sphere Propagation (MSP) framework, a rapid, spherebased approach…
