Devices. 2017;11(2):021004-021004-11. doi:10.1115/1.4036095 Figure Legend: Simulation setup. (a) How a patient would be positioned inside an MRI scanner. (b) The resulting geometry of the atrial fibrillation ablation task in the left atrium model [30]. The black markers are the desired targets for atrial fibrillation ablation. The black polygons around the pulmonary veins represent the circumferential lesions.
