-Norm Regularization in Volumetric Imaging of Cardiac Current Sources

Figure 3

Source estimation using -norm regularization for . (a) 58 active sources are located at left ventricle mid-anterior. (b) 127 active sources are located close to the right ventricle apex. Increasing the value increases the source extent such that -norm obtains too scattered source distribution while -norm provides overly diffused solution. Current magnitudes are normalized to 1.
