Abstract
The magnetic resonance signals in a magnetic resonance imaging apparatus are detected by a surface or localized coil assembly (D). To improve the field homogeneity and increase the signal-to-noise ratio when examining a region of interest deep within a subject, the surface coil assembly is configured with a first coil portion (22) and a second coil portion (24). The first coil portion is disposed along an exterior surface of the subject. The second coil portion is disposed parallel to the first coil portion and displaced outward a distance (44) from the first coil portion and the subject exterior surface. The first and second coil portions are electrically interconnected with an opposite current phase in a dipole pair such that the second current portion reduces the sensitivity of the first coil portion to magnetic resonance signals originating close to the surface of the subject.
