<p><P>PROBLEM TO BE SOLVED: To reduce artifacts in regard to a magnetic resonance imaging apparatus that scans a predetermined part displaced by a subject's body motion. <P>SOLUTION: The intensity of high-frequency region data DA2-DN2 of image k spaces SA-SN is corrected based on the intensity of center data A1-N1 of correction k spaces S<SB POS="POST">a1</SB>-S<SB POS="POST">n1</SB>collected by first scanning, and the intensity of center data A2-N2 of correction k spaces S<SB POS="POST">a2</SB>-S<SB POS="POST">n2</SB>collected by second scanning. The phase difference between the center data A1-N1 of the correction k spaces S<SB POS="POST">a1</SB>-S<SB POS="POST">n1</SB>collected by the first scanning, and the center data A2-N2 of the correction k spaces S<SB POS="POST">a2</SB>-S<SB POS="POST">n2</SB>collected by the second scanning, is obtained, and the phases of data DA2'-DN2' after the intensity correction of the high-frequency regions of the image k spaces SA-SN are corrected based on the phase difference. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
