Abstract:
1. A RF coil for magnetic resonance imaging apparatus, tuned to at least two different resonant frequencies, comprising: a first series resonant circuit comprising a loop coil made of a conductive material and one or more capacitors inserted into the loop coil, a first circuit connected in parallel to the first series resonant circuit, and a signal processing circuit connected in parallel to the first circuit, and having two or more different resonance frequencies, wherein: the first circuit comprises one or more capacitors and one or more inductors, and is connected in parallel with at least two series resonant circuits each having different resonance frequencies, the resonance frequencies of the at least two series resonant circuits also differ from resonance frequency of the first series resonant circuit, and each of the resonance frequencies of the RF coil are adjusted so as to be between the resonance frequency of the first series resonant circuit and the resonance frequencies of the at least two series resonant circuits.
