Phaseless Encoding

Classically encoded MRI signals are complex and therefore sensitive to uncontrolled phase variations. We propose an alternative spatial encoding method which leads to real positive signals and allows phase fluctuations to be removed by a simple magnitude calculation before the Fourier transform. The phase immunity of the method is demonstrated by recovering an image from a scan with unknown random receiver phase.
