Adaptive Local Neighborhood-based Neural Networks for MR Image Reconstruction from Undersampled Data

no code implementations1 Jun 2022 Shijun Liang, Anish Lahiri, Saiprasad Ravishankar

In brief, our algorithm alternates between searching for neighbors in a data set that are similar to the test reconstruction, and training a local network on these neighbors followed by updating the test reconstruction.

Sparse-view Cone Beam CT Reconstruction using Data-consistent Supervised and Adversarial Learning from Scarce Training Data

no code implementations23 Jan 2022 Anish Lahiri, Marc Klasky, Jeffrey A. Fessler, Saiprasad Ravishankar

This work focuses on image reconstruction in such settings, i. e., when both the number of available CT projections and the training data is extremely limited.
