    Abstract: A magnetic resonance imaging apparatus capable of suppressing noise caused by vibration of a gradient magnetic field coil and improving image quality is realized.A shim tray 22 is disposed between a static magnetic field generating magnet 4 and a gradient magnetic field generating coil 13. A large number of ferromagnetic shims are disposed in a large number of holes (screw holes) 24 formed in the shim tray 22. Vibration dampers 23 are disposed in holes formed in the shim tray 22 to reduce noise generated by vibration of the gradient magnetic field generating coil 13, which is propagated to the static magnetic field generating magnet through solid bodies and shakes the static magnetic field generating magnet, etc. It is hence possible to secure areas for arrangement of two means, i.e., static magnetic-field non-uniformity correcting means and vibration suppressing means, to reduce the noise caused by the vibration of the gradient magnetic field generating coil 13, and to suppress deterioration of image quality.

    Abstract: The present invention provides a magnetic resonance imaging system capable of performing spectrum measurement even when a magnetic resonant frequency changes during MRS measurement. A time-varying rate of a water magnetic resonant frequency is measured in advance before the MRS measurement. The amount of change in water magnetic resonant frequency during the MRS measurement is predicted from the measured time-varying rate. With the predicted value as the reference, a transmission frequency of an RF magnetic field irradiated in a signal suppression pulse sequence, a transmission frequency of an RF magnetic field for excitation and inversion and a received frequency at the detection of a magnetic resonance signal in a sequence of the MRS measurement are respectively set. A high-precision spectrum measurement is hence enabled.

    Abstract: In diffusion weighted imaging, motion monitoring navigation echoes are measured at every measurement of data after applying an RF excitation pulse, and one of them is set as a reference navigation echo. The reference navigation echo and other navigation echoes are one-dimensionally Fourier-transformed, a linear phase gradient thereof is calculated from those data, a linear phase gradient of the reference navigation echo is compared with those of other navigation echoes, and it is judged whether a difference therebetween is within an acceptable value or not. An echo signal corresponding to a navigation echo having the above difference being larger than the acceptable value is judged that correction based on the navigated motion correction is not applicable therein, and the image is produced by using an echo signal measured along with a navigation echo having the difference being the acceptable value or less. In this manner, a motion component included in the echo signal used for producing the image is made uniform and motion artifacts are eliminated.
