ABSTRACT:
A magnetic resonance imaging sequence synergistically combines Half Fourier Transform complex conjugation with shared echo imaging. The Half Fourier Transform complex conjugation reduces data acquisition time and permits the data acquisition per scan to be accomplished with a single RF transmission loop. The shared echo imaging provides multiple images of an image plane from a single scan, yet with different contrast and a larger number of slices. In an alternative embodiment, phase correction is provided between the non-shared echo responses.
