✦ Synopsis

A rapid automated method for reconstructing echo planar imaging (EPI) data has been developed and is shown to improve image quality by suppressing the troublesome ghost artifact. The algorithm can be applied without prior knowledge obtained from either reference scans or operator intervention. It first estimates, then improves iteratively, the parameters for a linear phase correction applied directly to the complex image data derived from odd and even echoes. The theory used to derive the criteria employed in the iteration provides insight into mechanisms that allow the process to work.

An image reconstruction technique for echo-planar imaging is proposed. This technique combines odd and even numbered echo signals. It is thus possible to reduce the frequency of the time-modulated gradient used in echo-planar imaging by 50%, and to reduce its amplitude by almost 50% for sinusoidal g
