MRI Recovery with Self-Calibrated Denoisers without Fully-Sampled Data

2 code implementations25 Apr 2023 Sizhuo Liu, Muhammad Shafique, Philip Schniter, Rizwan Ahmad

However, unlike traditional PnP approaches that utilize generic denoisers or train application-specific denoisers using high-quality images or image patches, ReSiDe directly trains the denoiser on the image or images that are being reconstructed from the undersampled data.

MRI Recovery with A Self-calibrated Denoiser

no code implementations18 Oct 2021 Sizhuo Liu, Philip Schniter, Rizwan Ahmad

The proposed method, called recovery with a self-calibrated denoiser (ReSiDe), trains the denoiser from the patches of the image being recovered.

Free-breathing Cardiovascular MRI Using a Plug-and-Play Method with Learned Denoiser

no code implementations8 Feb 2020 Sizhuo Liu, Edward Reehorst, Philip Schniter, Rizwan Ahmad

We compare the reconstruction performance of PnP-DL to that of compressed sensing (CS) using eight breath-held and ten real-time (RT) free-breathing cardiac cine datasets.
