Phase-encode acquisition order for three-echo SSFP using adaptive phased array ghost elimination (PAGE). The phase-encode acquisition order is varied in a cyclical manner to enable the adaptive calculation of a lower temporal resolution ghost-suppressed image used for computing B1-maps used in PAGE. In this example, 12 ky lines are acquired in four RF shots for each cardiac phase (1, ..., n, n + 1, n + 2, ..., N) during each heartbeat. However, the k-space matrix of each cardiac phase is acquired with a slightly varied view-ordering scheme achieved via changes in the phase-encode blip magnitudes. Note that the overall pattern of acquisition is noninterleaved but the ghosts in each image have different phase weighting depending on the acquisition order.
