摘要

PROBLEM TO BE SOLVED: To reduce a ghost caused by the attenuation of echo intensity like echo after an echo string and to reduce a ghost caused by a phase error in the MR imaging of an FSE method. ;SOLUTION: Each echo in the echo string is assigned to each segment to obtain data F (S1 to S3), an echo is next assigned to each segment in an inverse order in the state of inverting the order of the signal intensity at data F to obtain data R (S4 to S5) and data F and data R are added by each view to generate an image from the sum data (S6). In this case, the echo number of the echo string is desirably made even.;COPYRIGHT: (C)1999,JPO
