Filed: 2002-06-07
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the difference in signal intensity between echo signals on a k space in the fast spin echo (FSE) method, and to reduce artifacts caused by the difference in the signal intensity on a reconstructed image.  <P>SOLUTION: When eight echo signals S1-S8 are produced in order in the fast spin echo method, pairs of the echo signals such as S1 and S8, S2 and S7, S3 and S6, and S4 and S5 are formed. The same amount of a phase encoding gradient magnetic field Gp is applied to the echoes in the same pair, and the different amount is applied to the echoes in the different pair. The arithmetic mean of the data obtained from two echoes belonging to the same pair is calculated. An image is reconstructed after the placement of the arithmetic mean of the data on the k space. The effect caused by the decrease in the signal intensity by the passage of time because of T2 relaxation (transverse relaxation) is reduced by making the difference in the signal intensity after the addition small by the adding the echoes inside the pair.  <P>COPYRIGHT: (C)2004,JPO
