157 Computing volume potentials for noninvasive imaging of cardiac excitation RL LL RV L A B S RA Electrode Figure 3. A 3D computer model of the human thorax with the positions of the body surface electrodes (A) . The electrode positions were derived from the positions of the liquid-filled vitamin D capsules, appearing hyper intense on MRI. The thorax model contains multiple compartments (B). (RA right atrium; RV right ventricle; S spleen) RL LL H L Thorax RL LL LA L Thorax LV A B Figure 4. Locally refined multi compartment thorax 3D mesh (A) and volume mesh (B) . The mesh is error free and was generated in 25 seconds using freely available software on a 2.4 GHz single core on a laptop. No spatial smoothing was applied. (LA left atrium; LV left ventricle)
