Fast spin echo imaging plays a central role in clinical
imaging. Eddy current and other factors, however, can
introduce phase error in FSE sequences, which causes the
violation to CPMG condition and result in image
artifacts. The existing phase correction method works
well for 2D FSE, which assumes a linear phase error
along readout direction. However, to extend this
approach to 3DFSE, we may need assume a linear phase
error along both readout and slice direction, which may
not always be the case. Data acquisition with phase
cycling can be used to address this problem at the cost
of doubled scan time. In this work, we investigated
compressed sensing acceleration of data acquisition for
3DFSE phase correction using phase cycling.
