<P>PROBLEM TO BE SOLVED: To provide a system and a method by which slice selection magnetized preparation for moving bed MRI. <P>SOLUTION: The system includes a method (100) of magnetized preparation considering movement or translation of a patient during an imaging process. In the system, a frequency (108) to apply a magnetized preparation pulse to offset a preparation pulse (72) is adjusted or corrected. Thereby, the preparation pulse (72) and the imaging pulse can be alternately placed, and magnetized preparation without sacrificing other imaging variables or parameters defined for a concrete MR test are enabled. Thus contrast in a reconstructed image is improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI
