ABSTRACT:
A quadrature coil with a unique arrangement of vertical and horizonal mode coils allows for superior magnetic resonance imaging and spectroscopy through higher sensitivity and more uniform imaging over the region from the head to the crest of the aortic arch. The coil has vertical-mode conductors at approximately 30.degree., 150.degree., 210.degree.and 330.degree.with respect to a longitudinal axis, and horizontal-mode conductors at 90.degree.and 270.degree.. The horizontal-mode conductors are connected at the far end of the coil at an electrical midpoint of the horizontal-mode conductors, such that a voltage null will exist there when the coil is operated in vertical mode. The vertical and horizontal mode feedpoints are located at a head end of the coil, which is hinged into halves to permit easy access by and to a patient.
