Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and equipment for magnetic resonance imaging by an echo planner method which minimize distortion of an image due to ununiformity of a static magnetic field and which prevents overlapping of a ghost and a tomographic image.   <P>SOLUTION: Since an FOV is made to be a value obtained by adding the sizes of an image display area and a subject 1, the ghost generated at the position of the Nyquist frequency of the subject 1 is positioned outside of the image display area. Furthermore, since an FOV value can be twice as large as the image display area or smaller than this, it is possible to prevent the ghost from overlapping with the tomographic image of the subject 1 while minimizing the distortion of the tomographic image due to the ununiformity of the static magnetic field.  <P>COPYRIGHT: (C)2004,JPO
