A MAGNETIC RESONANCE APPARATUS WITH A DECOUPLING DETECTION SURFACE COIL

摘要

A surface coil used as a measuring coil in a magnetic resonance apparatus is divided into at least two coil portions having opposite directions of winding and enclosing two identical surface areas. An induction current generated in a coil portion by a transmission field is then always compensated for by a current generated in the other coil portion. When one or more of such butterfly coils are used no circuits to block interfering signals need be built into the electronic measuring circuit and the transmission field is not disturbed by the measuring coil.
