FIGURE 1.

A, Simulation pipeline and (B,C) example phase maps. The simulation pipeline begins with a 256 × 256 ImageNet image. Then, after random flipping and transposing, random phase and random ellipsoid cropping are applied. Then, the network input x_d has Gibbs ringing simulated along with noise and partial Fourier masking, followed by normalization. The target m_d images have the absolute value operation applied followed by spline resizing to the target image matrix size. An example of a phase map from this simulation is shown in (B), while a comparison in vivo phase map is shown in (C). Phase maps can have substantial variations that must be considered when applying partial Fourier imaging
