Patent ID: 7365537

Claim:
An MR data acquisition method comprising: acquiring data D — φ1 according to a steady-state pulse sequence specifying that the phase of an RF pulse is varied in order of 0, 1×φ1, 2×φ1, etc.; acquiring data D — φ2 according to a steady-state pulse sequence specifying that the phase of an RF pulse is varied in order of 0, 1×φ2, 2×φ2, etc., wherein φ1=φcenter+φstep and φ2=φcenter−φstep are established on the assumption that φcenter denotes a center phase, that is, a phase difference associated with the center of the portion of a line graph indicating a decrease in a signal strength, and that a phase width, that is, the width of the portion of the line graph indicating the decrease in a signal strength is provided as 2×φstep (where any of 0<φcenter<π, −π<φcenter<0, 0<φstep<π/2, and π/2<φstep <π is met); and generating an image using data D — φ1 and data D — φ2.
