Abstract
A family of high Q radio frequency coils for an NMR imaging system is provided. The coil family includes a transmitting coil for transmitting an r.f. field aligned with a given plane. The transmitting coil is used with one of the described receiving coils, each of which is responsive to NMR signals in a plane oriented orthogonally to said given plane. The receiving coils employ an open, arcuate configuration, which alleviates sensations of confinement characteristic of fully enclosing coil forms. Arcuate sections of the receiving coils are curved away from the patient, to decrease signal reception at areas from which meaningful signals cannot be gathered. To prevent interaction between the transmitting and receiving coils, means are provided for rendering each coil nonresponsive to NMR and radio signal frequencies when the coils are not being operated.
