Abstract

A double surface coil for a nuclear magnetic resonance apparatus as two individual coils, each individual coils being formed by two sub-coils connected in parallel. A series circuit of a capacitor and an inductor is connected in each sub-coil, with a series circuit of a capacitor and a controllable switch being connected in parallel with each inductor. By appropriate drive of switches, both individual coils, one individual coil by itself, or both individual coils in alternating operation can be activated.
