摘要： A method, system, and apparatus including a radio-frequency (RF) phased coil array for a magnetic resonance (MR) imaging apparatus that includes a first RF coil element tuned to a first frequency and configured to receive MR signals and a second RF coil element tuned to a second frequency different than the first frequency and configured to receive MR signals.

摘要： A method, system, and apparatus including a magnetic resonance (MR) coil system that includes an MR coil element, a high input Pre-amplifier having a high input impedance field-effect-transistor (FET) with an impedance of one of substantially equal to 500 ohms and greater than 500 ohms, and a conductive path. The conductive path has a first end coupled to the MR coil element and a second end coupled to the high input Pre-amplifier such that the MR coil element is coupled in series with the high input Pre-amplifier. Further, the conductive path is free of a matching network intervening between the MR coil element and the high input Pre-amplifier.
