Fast spin echo triple-echo Dixon (fTED) acquires one in-phase (IP) and two out-of-phase (OP) images in a single acquisition without interleave. A two-point Dixon processing algorithm is then used to independently process two pairs of IP/OP images. A potential drawback is that any processing failure in each processing will lead to incomplete local or global water and fat separation. In this work, we proposed and developed a jointly-processed region growing based two-point Dixon phase correction algorithm. The proposed approach was capable of reconstructing uniformly separated water and fat images even when anatomic regions are separated by large signal-void.
