Abstract
A radio frequency coil assembly includes an annular conductor () configured to support a sinusoidal electrical current distribution at a magnetic resonance frequency, and a radio frequency shield () shielding the annular conductor in at least one direction, the radio frequency shield including at least one of (i) a cylindrical shield portion () surrounding a perimeter of the annular conductor, and (ii) a planar shield portion () arranged generally parallel with the annular conductor. In a magnetic resonance scanner embodiment, a magnet () generates a static magnetic field (B), a magnetic field gradient system () is configured to superimpose selected magnetic field gradients on the static magnetic field, and said radio frequency coil assembly is arranged with the annular conductor generally transverse to the static magnetic field (B).
