NMR probe with multiple isolated coplanar surface coils.

摘要

An NMR antenna probe (10) has at least one substantially circular surface coil (11) arranged in a plane and a non-circular surface coil (12) which is preferably of substantially figure-8 shape and is substantially coplanar with the at least one circular surface coil. The figure-8 coil has a cross-over portion which is located substantially coaxial with the axis of the at least one circular surface coil. The circular coil corresponds to the least-NMR-sensitive nucleus, while the non-circular coil corresponds to the most-NMR-sensitive nucleus. The circular coil is positioned on the side of the NMR probe closest to the subject to be studied.
