| 摘要 |
The invention provides a method and apparatus for acquisition and analysis of data that displays a linear relationship or can be transformed into a linearized relationship, such as electrophysiological signal data from sensors such as those suitable for EEG, MEG, ECG and the like. The method, which can be implemented in computer software, includes computing a current density vector field by solving the related unweighted linear inverse problem, pre-processing the current density vector field using an sLORETA transformation, computing a diagonal weighting matrix so that its entries are determined by a monotonically increasing function of their corresponding values in the sLORETA method outputs, and computing the current density vector field by solving the related weighted linear inverse problem. The outputs of the method can be stored in computer files for display on suitable monitors.
