A novel two-point fat water separation
method using safest path region growing with self-feeding phasor estimation
algorithm is proposed. The phasor map is estimated by multiresolution region
growing scheme where the seed pixels identification and region growing scheme
is performed independently between coarser resolutions, avoiding the erroneous
propagation between resolutions. The “self-feeding” mechanism when merging the
phasor maps ensures the reliability of seed pixels selection at the finest
resolution. The algorithm was tested on c-spine and abdomen data and shown to
be robust in fast varying field and disjoint areas.
