ABSTRACT:
Provided is an RF coil which can highly efficiently and uniformly irradiate a RF magnetic field having two or more magnetic resonance frequencies close to each other, and receive magnetic resonance signals of two or more magnetic resonance frequencies close to each other with high sensitivity and uniform sensitivity profile in an MRI apparatus. Two or more frequencies to which the coil is tuned are adjusted so as to be between resonance frequencies of series resonant circuits constituting the RF coil.
