Abstract
A local gradient coil adapted for use with stereotaxic devices includes an opening in the coil form positioned to minimize the disruption to the gradient fields and a bearing for moving the form with respect to the stereotaxic frame so that the opening may be limited in area and yet provide essentially unrestricted access to the patient. The windings in the neighborhood of the opening may be diverted by modifying the stream function of the windings in a manner to minimize the effect of the opening on the gradient field.
