Magnetocardiography Current Source Estimation using Multiple Spatial Filters

In this study, cardiac current source localization was simulated using the spatial filter method. We estimated sources data from two measurement surfaces, i.e., front and back of subject, to reduce large extension in depth direction. Three methods for creating filters were developed exact low-resolution brain electromagnetic tomography method based on different creation procedures. The first is a general that has been conventionally used create (64ch filter) 64ch sensor side. second (128ch sensors sides as 128ch sensor. third separately use them one (2 × filter). case, Tikhonov regularization parameters can be determined sides, optimum noise immunity given each. accuracy three types examined simulation MCG data. results show 2 64 highest estimation suppresses sources.
