Model-based free-breathing cardiac MRI reconstruction using deep learned \& STORM priors: MoDL-STORM

no code implementations10 Jul 2018 Sampurna Biswas, Hemant K. Aggarwal, Sunrita Poddar, Mathews Jacob

We introduce a model-based reconstruction framework with deep learned (DL) and smoothness regularization on manifolds (STORM) priors to recover free breathing and ungated (FBU) cardiac MRI from highly undersampled measurements.

Two step recovery of jointly sparse and low-rank matrices: theoretical guarantees

no code implementations5 Dec 2014 Sampurna Biswas, Sunrita Poddar, Soura Dasgupta, Raghuraman Mudumbai, Mathews Jacob

We introduce a two step algorithm with theoretical guarantees to recover a jointly sparse and low-rank matrix from undersampled measurements of its columns.
