ABSTRACT:
A NMR Quadrature Detection Array includes two generally linear arrays; one oriented in a horizontal plane and sensitive to vertically oriented changing magnetic flux, and the other oriented in a vertical plane bisecting the horizontal plane and sensitive to horizontally oriented flux changes. Each horizontal coil is electronically paired with a vertical coil such that their NMR signals are combined in a quadrature fashion before transmission to the NMR system preamplifier. The coil arrays are sized to accommodate easy positioning within the NMR system table top assembly as well as to facilitate rapid and easy patient positioning about the coil elements.
