Abstract: The invention provides for a magnetic resonance imaging system (100) comprising a main magnet (104) for generating a main magnetic field within an imaging zone (108). The magnetic resonance imaging system further comprises an RF coil (114) for acquiring magnetic resonance data (164) from the imaging zone, wherein the RF coil comprises multiple RF ports (124, 412, 414, 416, 500, 502, 702, 1004, 1006). The RF coil comprises a switch unit (120) for at least one of the multiple RF ports to individually couple or uncouple the at least one of of the multiple RF ports from the RF coil. The magnetic resonance imaging system further comprises a radio-frequency system (125) for supplying radio-frequency power to each of the multiple RF ports and an RF matching detection system (122) for measuring impedance matching data (166) between the radio-frequency system and the RF coil.

Abstract: A radio frequency volume coil (136; 236) for use in a magnetic resonance examination system (10), comprising:—a radio frequency shield (148; 248),—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), wherein—at least two axially arranged radio frequency conductive members electrically interconnect the radio frequency conductive loop members (138; 238) as interconnecting members (144; 244), and—at least two of the axially arranged radio frequency conductive members are axially arranged in an aligned manner at an azimuthal position within the range between azimuthal positions of the at least two interconnecting members (144; 244), and electrically serve as shield-connecting members (146; 246) for one of the two radio frequency conductive loop members (138; 238) to the radio frequency shield
