    摘要: In one example, an antenna is disclosed comprising a first, outer conductor, at least one inner conductor within the first outer conductor, and a second outer conductor surrounding the first outer conductor. The second outer conductor may define a plurality of holes therethrough. The at least one inner conductor may comprise a plurality of inner conductors. At least two of the plurality of inner conductors may be connected to each other in series, across a capacitor. At least two of the plurality of inner conductors may be connected to each other in parallel, across a capacitor. The at least one inner conductor may be sufficiently surrounded by the first outer conductor to shield the inner conductor from receiving a radiofrequency signal.

    摘要: 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.
