Rotating body coil apparatus for interventional magnetic resonance imaging

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.
