Abstract

Based on a 3-D inhomogeneous simulative body torso model, the influence of various boundary conditions on inverse recovered epicardial potential maps (EPM) was studied by boundary element method (BEM). The result shows that the precision of EPM calculated under incomplete boundary conditions will meet the clinical requirements, as long as the incomplete boundary conditions still contain the extremum area which often appears at the breast area.
