(a) The signal from the precessing proton spins which is acquired by the MR receiver is represented as a complex number with real (R) and imaginary (I) components from which a pixel-by-pixel signal magnitude and phase can be calculated. (b) Reconstruction of the real component of the magnetization. (c) Reconstruction of the imaginary component of the magnetization.(d) The calculated magnitude signal. (e)The calculated phase signal.
