| Abstract: | For it is briefly definite, ECD model has been widely used in MCG, such as WPW syndrome, ectopic beats and arrhythmia, which also get application in BSPM measurement. MCG source localization methods with ECD are discussed, as well as simulation results using ECD from clinical research, phantom and animal studies, effect from volume conductor models on source localization. |
