Illustration of the phase unwrapping procedure. (A) The original wrapped phase image in basal ganglia area at 7 T, TE = 23.2 ms. (B) The fitted macroscopic phase image using an eighth-order polynomial function. (C) Subtraction of fitted phase background from the original wrapped phase. (D) Unwrapped phase image after trim the pixel values into range [−p, p].
