Figure 2From: Pseudo current density maps of electrophysiological heart, nerve or brain function and their physical basisVisualization of the atrial activation for the first time instant marked by a cursor in Fig.1. Left: B z -map drawn as isocontour maps with a magnetic flux density difference of 0.5pT between adjacent contour lines (red: positive, i.e. directed towards the subject; blue: negative; black: B z = 0). Right: the corresponding pseudo current density map.Back to article page
