Key result
Magnetocardiographic localization of an amagnetic catheter in a torso phantom was more accurate than body surface potential mapping, with mean 3D errors of 2±1 mm vs 4±1 mm at a 38 mm depth.
Why the study?
Does MCG mapping improve the accuracy of nonfluoroscopic catheter localization compared to BSPM in a thorax phantom?
Does MCG mapping improve the accuracy of nonfluoroscopic catheter localization compared to BSPM in a thorax phantom?
MCG mapping is more accurate than BSPM for nonfluoroscopic 3-dimensional localization of an amagnetic catheter in a realistic torso phantom.

MCG localization outperforms BSPM in torso phantom; leaves open translation to clinical catheter mapping.
Fenici et al. (1998) studied Electrophysiology mapping. Magnetocardiographic (MCG) localization vs. Body surface potential mapping (BSPM) was evaluated on 3-dimensional localization error. Magnetocardiographic localization of an amagnetic catheter in a torso phantom was more accurate than body surface potential mapping, with mean 3D errors of 2±1 mm vs 4±1 mm at a 38 mm depth.
