The aim of this study is to provide a novel method for extending the field of view in lumber spine biomagnetic imaging.

The extension of the field of view is achieved by combining multiple measurements using positional relationship between the sensor array and the subject¡¯s body; the relationship is obtained using marker measurements performed together with each magnetic field measurement.

Functional lumber spinal cord imaging is performed by using the spatial filter technique. We measure spinal cord evoked magnetic field from five healthy volunteers by applying 4-Hz electric stimuli at their peroneal nerve. Our proposed large field-of-view imaging shows clear nerve conduction in the lumber spine region for all five subjects, demonstrating its effectiveness.
