Abstract
An MRI system receive coil arrangement 3 for use with a main MRI scanner arrangement. The arrangement includes at least one primary receive coil 6 having a first impedance at a predetermined frequency and a first size defined by a cross-sectional area bounded by the primary receive coil and at least one auxiliary receive coil 7 having a second impedance at said predetermined frequency and a second size defined by a cross-sectional area bounded by the auxiliary receive coil wherein the first impedance is lower than the second impedance and the first size is larger than the second size.
