Abstract

A double surface coil for a nuclear magnetic resonance apparatus has two individual coils which are connectable to a transmission/reception circuit via a matching network. The coils are connected together at a junction. Each coil has a controllable switch connected between the junction and the matching circuit. The individual surface coils can thus be controlled with a low number of controlled elements in any desired operating mode.
