摘要：
A method for diagnostic imaging includes measuring undersampled data y with a diagnostic imaging apparatus； linearly transforming the undersampled data y to obtain an initial image estimate {tilde over (x)}； applying the initial image estimate {tilde over (x)} as input to a generator network to obtain an aliasing artifact-reduced image x̆； as output of the generator network, where the aliasing artifact-reduced image x̆； is a projection onto a manifold of realistic images of the initial image estimate {tilde over (x)}； and performing an acquisition signal model projection of the aliasing artifact-reduced x̆； onto a space of consistent images to obtain a reconstructed image {circumflex over (x)} having suppressed image artifacts.
