1. A few-view computed tomography (CT) image reconstruction system, the system comprising:
a preprocessing module configured to apply a ramp filter to an input sinogram to yield a filtered sinogram;
a first generator network configured to receive the filtered sinogram, to learn a filtered back-projection operation and to provide a first reconstructed image as an output, the first reconstructed image corresponding to the input sinogram; and
a discriminator network configured to determine whether a received image corresponds to the first reconstructed image or a corresponding ground truth image, the first generator network and the discriminator network corresponding to a Wasserstein generative adversarial network (WGAN), the WGAN optimized using an objective function based, at least in part, on a Wasserstein distance and based, at least in part, on a gradient penalty.
