Abstract
A magnetic resonance image receiving coil includes a first balloon having a longitudinal axis. An internal surface of the first balloon defines an internal inflatable chamber. A second balloon has a longitudinal axis. The second balloon is disposed about the first balloon. A plurality of longitudinally extending grooves are disposed in one of an external surface of the first balloon and the internal surface of the second balloon. A first wire is disposed in at least one of the grooves. A second wire is disposed in at least a second one of the grooves. Each of the first wire and the second wire is adapted to be electrically connected to an MRI apparatus. In accordance with an alternate embodiment, the first and second wires are disposed in grooves in a sheath which is disposed between the first and second balloons. In accordance with a further alternate embodiment, the first and second wires are disposed in guide tubes that are connected to the external surface of a balloon.
