Patent ID: 7852076

Claim:
A magnetic resonance imaging system comprising: means for generating a static magnetic field; gradient magnetic field generating means for generating a gradient magnetic field; RF magnetic field generating means for generating an RF magnetic field; measuring means for measuring a magnetic resonance signal generated from a target; and sequence control means configured to set operating conditions to respective portions of the gradient magnetic field generating means, the RF magnetic field generating means and measuring means; said sequence control means being configured to: (1) execute a water suppression sequence for applying the RF magnetic field and the gradient magnetic field to the target to thereby suppress a signal of water; (2) determine that a magnetic resonant frequency of water has been shifted when the calculated signal strength of water signal peak is increased to a predetermined value or more, and (3) set a transmission frequency of the RF magnetic field irradiated and/or set a received frequency at the detection of the magnetic resonance signal.
