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.
