摘要: The present invention is directed to an elliptical birdcage coil which reduces time and effort upon manufacturing production cost, with less variations in performance. There provided a high frequency unit made up of the having plural capacitors arranged at least on either ring conductors rung conductors, capacitance being uniform respect each conductor type are placed. In this coil, value inductance arrangement determined such manner that becomes identical arranged.
