Patent number: 6995561Abstract: A multiple channel array coil for magnetic resonance imaging (MRI) is disclosed. In an exemplary embodiment, the array coil includes a plurality of conductive strips formed within a dielectric medium. The conductive strips are further arranged into a generally cylindrical configuration, with each of the strips having a length (l), selected to cause each of the strips to serve as a resonator at a frequency corresponding to a proton MRI frequency. Thereby, the generally cylindrical configuration of conductive strips forms a multiple channel, volume resonator in which each of the strips is isolated from the remaining strips.Type: GrantFiled: April 1, 2002Date of Patent: February 7, 2006Assignee: GE Medical Systems Global Technology Company, LLCInventors: Eddy Benjamin Boskamp, Ray F.
