DOUBLE RESONANT TRANSMIT RECEIVE SOLENOID COIL FOR MRI

摘要

A magnetic resonance system (8) comprises a radio frequency coil (36) which can resonate at least at first and second predetermined resonance frequencies. A tuning resonant circuit (110, 132) is serially coupled to the radio frequency coil (36). The tuning resonant circuit (110, 132) includes tuning components (Cp, Lp; Cp, Ch, Lh). Values of the tuning components (Cp, Lp; Cp, Ch, Lh) of the tuning circuit (110, 132) are selected such that a sensitivity profile of the radio frequency coil resonating at the first frequency substantially matches a sensitivity profile of the radio frequency coil resonating at the second frequency.
