Abstract: <P>PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging device capable of obtaining a good image without image strain by correcting a phase error component caused by static magnetic field nonuniformity.  <P>SOLUTION: The constitution of this device is shown in Fig. The measured data to which Fourier transformation is performed not only to the reading direction but to the phase encode direction is corrected for the image strain caused by static magnetic field nonuniformity by phase-rotating so that the phase contained in the pre-measured data measured beforehand at each echo time becomes zero. FFT (fast Fourier transformation) is performed to the image obtained by a reference measurement for calculating a static magnetic field nonuniform component Sn(x, y), and the static magnetic field nonuniform component is calculated(Step 201, 202). The image Sn(x, y) at the time of each echo measurement time is made by performing 2DFFT using only the data at the same echo measurement time among the measured data, and a static magnetic field nonuniform component Bn(x, y) at each echo measurement time is corrected (Step 301, 302). A correction data S'n(x, y) is returned to a measurement space by reverse FFT, is re-arranged to the original phase encode position, and is made to a 1 measurement space data by adding a data IFäS'n(x, y)}(Step 303, 304).  <P>COPYRIGHT: (C)2005,JPO&NCIPI
