Radio frequency volume coil with improved space and access for use in a magnetic resonance examination system
Abstract:
A radio frequency volume coil (136; 236) for use in a magnetic resonance examination system (10) includes a radio frequency shield (148; 248), and a pair of radio frequency conductive loop members (138; 238) spaced along a common longitudinal axis (140; 240), a plurality of axially arranged radio frequency conductive members electrically connected to at least one of the radio frequency conductive loop members (138; 238). At least two axially arranged loop coil interconnecting radio frequency conductive members (114; 244) electrically interconnect the radio frequency conductive loop members (138; 238). At least two of the axially arranged shield connecting radio frequency conductive members are axially arranged in an aligned manner at an azimuthal position within a range between azimuthal positions of the at least two loop coil interconnecting members (144; 244), and electrically serve and connect one of the two radio frequency conductive loop members (138; 238) to the radio frequency shield (148; 248). At least one installation space (152; 252) within an inner volume of the radio frequency volume coil (136; 236) is accessible from outside the radio frequency volume coil (136; 236) at least in a radial direction (56) within the range between the azimuthal positions of the two loop coil interconnecting members (144; 244) and within a range of axial directions between axial positions of ends of the shield-connecting members (146; 246) that are distal to the radio frequency conductive loop member (138; 238).
