ABSTRACT:
An antenna structure for magnetic resonance imaging includes a plurality of spiral wound, generally planar coils spaced axially from one another. The plural coils may be mounted on a rigid frame in the desired relative positions and the subject may be inserted in the space defined by the frame. Alternatively, the individual coils can be separately supported on the subject, as by mounting the coils to the subject. Desirably, a part of the subject's body extends through central apertures in one or more of the coils.
