    摘要： A radio frequency volume resonator mounted on a generally cylindrical dielectric support can be operated in quadrature at one or more NMR frequencies. The resonator consists of four axially distributed high frequency ring current paths and a dielectric support, at least four high frequency current paths interconnect each pair of adjacent ring paths, at least one discrete capacitor is placed in each current loop but arranged so that none of the ring current paths is interrupted by a capacitor.

    摘要： A MRI coil having an axis and a first end and an opposite second end with respect to said axis includes a first ring element at the first end, a second ring element, a third ring element, a fourth ring element at the second end where the first ring element encompasses a smaller area than each of the second, third, and fourth ring elements. The coil also includes a plurality of axial elements connected between the first, second, third and fourth ring elements. The third and fourth ring elements are axially closer than the first and second ring elements.
