    摘要: An imaging coil (12) includes multiple end rings (52). A center ring (53) extends parallel to and is coupled between the end rings (52). Multiple legs (86) are coupled between the end rings (52) and the center ring (53). The end rings (52) may have a first radius (R1) that is greater than a second radius (R2) of the center ring (53). The imaging coil (12) may include more than 16 legs. The imaging coil (12) may include multiple capacitor groupings (98) coupled along the end rings (52), each capacitor grouping (98) has multiple capacitors (102) with a coverage area width (W) greater than 5.0 cm. The center ring (53) may be coupled to a ground reference (110) and has low impedance such that the center ring (53) is effectively shorted to the ground reference (110).

    摘要: A rotating body coil assembly for use with an open MR magnet for imaging at least a portion of a subject comprises a resonant structure configured to rotate about the subject and to permit access to the subject during imaging. The body coil assembly comprises first and second end ring assemblies positioned on opposing sides of the imaging space. The first and second end ring assemblies are each configured to energize the body coil assembly. A plurality of element assemblies are disposed between and connecting the first and second end ring assemblies for providing structural support and electrical isolation of the body coil assembly. A base assembly is coupled to the first and second end ring assemblies and at least one of the element assemblies. The base assembly is adapted to rotate the first and second end ring assemblies in cooperation with the plurality of element assemblies about the portion of the subject while the portion of the subject is inside the imaging space for permitting access to the subject during imaging.
