Abstract
A radio frequency coil unit (10) for use in a magnetic resonance imaging system, the radio frequency coil unit (10) comprising: at least one electrically insulating substrate (18); at least one radio frequency coil member (12) disposed at a first side (22) of the electrically insulating substrate (18); a first capacitor member (26) disposed at the first side (22) of the electrically insulating substrate (18) and galvanically connected to the at least one radio frequency coil member (12); a second capacitor member (28) disposed at a second side (24) of the electrically insulating substrate (18) which is opposite of the first side (22); wherein the first capacitor member (26) and the second capacitor member (28) at least partially overlap in a direction (20) perpendicular to a surface of the electrically insulating substrate (18); and wherein the at least one radio frequency coil member (12), the first capacitor member (26) and the second capacitor member (28) are part of a radio frequency resonance circuit having a resonance frequency that coincides with the Larmor frequency, which is determined by a magnetic field strength of the magnetic resonance imaging system and the species of…
