Single Image Compressed Sensing MRI via a Self-Supervised Deep Denoising Approach

no code implementations22 Nov 2023 Marlon Bran Lorenzana, Feng Liu, Shekhar S. Chandra

Popular methods in compressed sensing (CS) are dependent on deep learning (DL), where large amounts of data are used to train non-linear reconstruction models.

Multi-scale MRI reconstruction via dilated ensemble networks

no code implementations7 Oct 2023 Wendi Ma, Marlon Bran Lorenzana, Wei Dai, Hongfu Sun, Shekhar S. Chandra

As aliasing artefacts are highly structural and non-local, many MRI reconstruction networks use pooling to enlarge filter coverage and incorporate global context.

Fractal Compressive Sensing

no code implementations15 Sep 2023 Marlon Bran Lorenzana, Benjamin Cottier, Matthew Marques, Andrew Kingston, Shekhar S. Chandra

Compare reconstruction quality of the sampling schemes under various reconstruction strategies to determine the suitability of p. frac for CS-MRI.

Transformer Compressed Sensing via Global Image Tokens

1 code implementation24 Mar 2022 Marlon Bran Lorenzana, Craig Engstrom, Shekhar S. Chandra

To showcase this development, we replace CNN components in a well-known CS-MRI neural network with TNN blocks and demonstrate the improvements afforded by KD.
