摘要

A biomedical method of forming images of current sources inside a subject or body involves defining a grid extending over a first region and contg. a number of grid points. A magnetic field produced by current sources inside part of the body corresp. to the defined grid is measured. The distribution of the current sources on the defined grid is determined from the measured magnetic field. The grid is modified to extend over a second region smaller than the first region to improve the resolution of the current sources distributed on the grid. ADVANTAGE - High resolution to desired enlargement with reduced number of sensor coils.
