Patent ID: 8198894

Claim:
A high frequency magnetic field coil of a magnetic resonance imaging apparatus whose resonance frequency is a magnetic resonant frequency of a first nuclide, comprising: a sub coil disposed at a point at which it can instantaneously inductively couple with the high frequency magnetic field coil; and a conduction control unit that controls conduction of the sub coil, wherein, at a time of the conduction, the sub coil instantaneously inductively modifies the resonance frequency of the high frequency magnetic field coil to be a magnetic resonant frequency of a second nuclide that has a higher magnetic resonant frequency than the magnetic resonant frequency of the first nuclide, wherein, at a time of no conduction, the resonance frequency of the high frequency magnetic field coil also instantaneously reverts to the resonant frequency of the first nuclide, and wherein the magnetic resonance imaging apparatus is capable of performing plural nuclide imaging over the entire area of the subject with only the high frequency magnetic field coil being resonant.
