Unsupervised Sparse-view Backprojection via Convolutional and Spatial Transformer Networks

1 Jun 2020 Xueqing Liu Paul Sajda

Many imaging technologies rely on tomographic reconstruction, which requires solving a multidimensional inverse problem given a finite number of projections. Backprojection is a popular class of algorithm for tomographic reconstruction, however it typically results in poor image reconstructions when the projection angles are sparse and/or if the sensors characteristics are not uniform...
