Abstract:
1. A dual coil system for magnetic resonance imaging, the system comprising: a surface coil; a volume coil having a cylindrical non-magnetic core module having an outer surface and a longitudinal axis, a cylindrical bore extending through the core module along the longitudinal axis and defining an inner surface; a plurality of conductive strip lines, the strip lines extending parallel to the longitudinal axis on the inner surface of the core module; a pair of circuit boards carried at the ends of the core module; and a plurality of resonating elements, each of the resonating elements including one of the strip lines and at lease one tuneable capacitor, wherein the volume coil includes features formed therein that permit the volume coil to be slidably moved along the longitudinal axis along guide members associated with a frame.
