Combining phase images from multiple channels is a
difficult problem hindered by challenges such as phase
wrapping, noise and the unknown phase offset between
each of the channels. We present here a method which
reconstructs the underlying objects phase image (i.e.,
tissue phase), as well as the channels phase offsets,
from a single Multi-Echo Gradient Echo (MEGE) scan,
without requiring a reference scan.
