PROBLEM TO BE SOLVED: To provide a technique that strikes a balance between a speeding up and a high picture quality, by striking a balance between a wide sensitivity region and a deep high sensitivity without complicating a configuration, in an array coil of multi-channel of the MRI device.SOLUTION: An RF coil (array coil) of a magnetic resonance imaging apparatus with two or more sub-coils is provided. At least one sub-coil is a first sub-coil with a resonance frequency in the single different from a magnetic resonance frequency. The first sub-coil is adjusted so as to resonate in the frequency same as the magnetic resonance frequency by magnetic coupling with a second sub-coil being at least one other sub-coil. The input-output terminals of the first sub-coil and the second sub-coil are connected to low input/output impedance signal processing circuits being different, respectively.SELECTED DRAWING: Figure 6 |
