Patent ID: 8188739

Claim:
A nuclear magnetic resonance imaging apparatus comprising; an imaging means comprising a gradient magnetic field application means which applies a gradient magnetic field to a subject placed on a static magnetic field space, a high-frequency magnetic field pulse irradiating means which irradiates a high-frequency magnetic field pulse on the subject and a receiving means which receives nuclear magnetic resonance signals generated from the subject, a sequence control means which controls the imaging means and implements a signal suppression pulse sequence including irradiation of at least one high-frequency magnetic field pulse for suppressing signals generated from a given atomic nucleus, a pulse amplitude adjusting means which adjusts amplitude of the high-frequency magnetic field pulse to be used in the signal suppression pulse sequence, wherein the pulse amplitude adjusting means comprises an optimal pulse amplitude calculation means, which calculates an optimal pulse amplitude in the signal suppression pulse sequence based on absolute values and phase values of multiple nuclear magnetic resonance signals obtained by implementing the signal suppression pulse sequence in multiple conditions with different pulse amplitude.
