159 Computing volume potentials for noninvasive imaging of cardiac excitation Mesh size 0.5 cm Mesh size 1.5 cm Le/ Right RL L H Figure 6. Anterior view of the thorax. Shown are the computed BVP during one heartbeat. (a- j) Mesh edge size is 0.5 cm. (k-t) Mesh edge size is 1.5 cm. The crude edges are artifacts from segmentation, performed in 3D. Since topology had to be preserved, no spatial smoothing was applied. RL LL H L S RL LL H L S A B Figure 7. The impact of variable organ conductivity on BVP. A smaller sigma of the lung tissue leads to an increased breakthrough of the potential field (A), compared to simulations in a homogeneous torso model (B) .
