  • Patent number: 4757290
    Abstract: A circularly polarized radio frequency probe for use in magnetic resonance systems, the probe comprises four effective "saddle coils" arranged to define a single cylinder. The saddle coils each comprise a pair of 120 degree arcuate conductor sectors separated by longitudinal conductors. RF power is coupled to each of said "saddle coils" so that first and second pairs of said saddle coils generate first and second fields normal to each other.

  • Patent number: 4648405
    Abstract: An improved body probe for use in high field Mr data acquisition systems having a two feed balanced inductor circuit using series capacitors to control the effect of stray capacitance and coupling resistors connected across the coil approximately mid-way between the two feed points. This arrangement is superior to prior art body probes operating in whole body high field MR imagers.
