An elasticized net modeling the pericardium

In boundary element models used for computing pericardial potentials it is necessary to use individual geometry. This data is usually obtained from MR imaging. The triangulations describing the pericardium of individual subjects are not automatically node-to-node comparable, which hampers the analysis of inter-individual variability. This problem is now solved by a placing a stretchable, elasticized net mound the pericardial surface in such a way that anatomical landmarks defined on the pericardial net coincide with anatomical landmarks on the pericardial surface
