1. A low-dose imaging method, comprising:
receiving a sparse image set of a portion of a patient's anatomy, wherein the sparse image set comprises a plurality of globally-distributed artifacts;
up-sampling the sparse image set, in a sinogram domain and using a first neural network trained in the sinogram domain, to yield an up-sampled sinogram in which the first neural network has filled in at least some of the plurality of globally-distributed artifacts;
generating, from the up-sampled sinogram, an initial reconstruction; and
removing, from the initial reconstruction and using a second neural network trained in a slice domain, one or more artifacts in the initial reconstruction to yield a final output volume.
