Abstract

A multiple tuned birdcage coil structure has a plurality of birdcage coils arranged coaxially one inside another around a central axis. Each of the birdcage coils has two conductor rings separated along the central axis and a plurality of mutually separated and parallel linearly elongated conductor legs and generates B1 field which rotates around the central axis by a specified twist angle between the two rings. The twist angles of different ones of these birdcage coils are different by an integral multiple of 360 degrees such that the assembled birdcage coils are mutually inductively transparent. Such a multiple tuned birdcage coil structure may be formed by assembling individually prepared single tuned birdcage coils each having a specified twist angle with a cylindrically shaped insulating bodies in between. A double tuned birdcage coil structure with two birdcage coils may be produced by providing a single printed circuit substrate with metallic sheets laminated on an insulating sheet, etching the metallic sheets to form appropriate patterns, rolling the substrate into a cylindrical form and soldering together appropriate portions of ring-forming parts to form conductor rings directly connected to or capacitively coupled to spirally birdcage legs.
