Abstract
A method and apparatus for performing biomagnetic imaging to determine the location and intensity of current sources within a subject includes a sensor unit for sensing the magnetic field within the subject and for providing sensing signals. A signal processor defines a grid having multiple grid points and performs inverse estimation to determine the distribution of current sources on the defined grid based on the sensing signals. The signal processor then modifies the grid to improve the resolution of the current sources distributed on the grid. A control unit controls the operation of the signal processor and processes image data to provide magnified and non-magnified displays on a display unit. The biomagnetic imaging method and apparatus can be combined with a system for providing magnetic resonance imaging data so as to produce a superimposed display including an MRI image and a biomagnetic image.
