DeepPET: A deep encoder-decoder network for directly solving the PET reconstruction inverse problem

no code implementations • 20 Apr 2018 • Ida Häggström, C. Ross Schmidtlein, Gabriele Campanella, Thomas J. Fuchs

To overcome this problem we present a novel PET image reconstruction technique based on a deep convolutional encoder-decoder network, that takes PET sinogram data as input and directly outputs full PET images.
