ABSTRACT:
A quadrature antenna for magnetic resonance imaging systems is provided which includes first and second channels, each of these channels comprising a coil pair. Each of the four coils comprising the antenna is elliptical in shape and lies in a respective plane. The center point of each coil coincides with a reference point on the longitudinal axis of the antenna. The minor axes of the coils of the first channel coil pair are colinear. The minor axes of the coils of the second channel coil pair are also colinear with each other and are perpendicular to the minor axes of the coils of the first channel coil pair. Each of the four planes is inclined approximately forty five degrees (45.degree.) with respect to the longitudinal axis of the antenna.
