Abstract

Apparatus for use in a magnetic resonance imaging system, the imaging system generating a magnetic imaging field in an imaging region (5), the apparatus including at least one coil for at least one of transmitting, receiving or transceiving an electromagnetic field, a field component (4) (such as a coil or a shield) and a drive (6) coupled to the field component for moving the field component (4) relative to the imaging region (5) to thereby modify the electromagnetic field during imaging process. The same concept can also be applied to nuclear imaging or nuclear spectroscopy apparatus.
