USE OF MEASUREMENTS MADE IN ONE ECHO TRAIN TO CORRECT RINGING IN SECOND TO AVOID USE OF PHASE ALTERNATED PAIR IN THE SECOND
摘要
Estimates of ringing produced by short recovery pulse sequences (CPMG or modified CPMG) are used to improve the effects of ringing in a conventional CPMG or modified CPMG sequences. This is an effective method for removal of ringing when the ringing is varying over a time interval that would be spanned by a phase alternated pair of conventional sequences. By use of frequency dithering, ringing due to the excitation pulse and the refocusing pulses can be removed.
