Abstract
In an MRI system a fast spin echo pulse sequence is employed to acquire data for producing an image. The phase of successive RF refocusing pulses in the sequence is shifted by a sweep factor and an odd echo signal and an even echo signal is acquired for each view. Two k-space data sets are formed, one by summing the even and odd echo signal pairs and the other by subtracting the echo signal pairs. Two magnitude images are reconstructed from the respective k-space data sets and an output image is formed by combining these two images.
