Abstract
A shielded birdcage-type radiofrequency (RF) resonance coil having a non-circular cross-sectional shape corresponding to a Cassinian oval. The placement of longitudinal conducting elements in the former of the coil is determined numerically by conformal mapping of the equally distributed positions of the conductors in a circular coil onto a Cassinian oval.
