RADIATION-TRANSPARENT, LOW-COST, LIGHTWEIGHT, VERSATILE, COMPOSITE RADIO FREQUENCY COIL FOR MRI

摘要

A radio frequency coil (34), for use in a medical modality including at least a magnetic resonance examination system (10), comprises: a right hollow cylinder-shaped patient bore lining (36), an inner carrier member (40) that is fixedly attached to an outwardly directed surface of the patient bore lining (36), a radio frequency antenna (42), fixedly attached to an antenna carrier member (44) made from a composite material, which in turn is fixedly attached to an outwardly directed surface of the inner carrier member (40), at least one outer carrier spacer member (48), arranged on at least one out of the at least one radio frequency antenna (42) or an outwardly directed surface of the antenna carrier member (44), and providing a free end-to-end space (50) in a direction parallel to the center axis (38) of the patient bore lining (36), a right hollow cylinder-shaped outer carrier member (52) with a center axis (54), which in an operational state is arranged in parallel to the center axis (38) of the patient bore lining (36), and is in mechanical contact with outwardly directed surfaces of the outer carrier spacer members (48), and a shell member (58) that is in mechanical contact with an outwardly directed surface of the outer carrier member (52); and a medical modality including at least a magnetic resonance examination system (10) with such radio frequency coil (34).
