Abstract
Systems, methods and apparatus are provided through which in some embodiments a magnetic resonance imaging (MRI) system includes one or more magnetic shield coils positioned asymmetrically in the casing and also positioned in close proximity to one of two apertures of an inner bore of the MRI system. In those embodiments, the position of the one or more magnetic shield coils provides an asymmetric magnetic stray field during operation of the MRI system, which in turn allows operation of electronic medical diagnostic equipment or electronic medical monitoring equipment in close proximity to the MRI.
