Clean self-supervised MRI reconstruction from noisy, sub-sampled training data with Robust SSDU
Robust SSDU trains the reconstruction network to map from a further noisy and sub-sampled version of the data to the original, singly noisy and sub-sampled data, and applies an additive Noisier2Noise correction term at inference.
A theoretical framework for self-supervised MR image reconstruction using sub-sampling via variable density Noisier2Noise
The development and understanding of self-supervised methods, which use only sub-sampled data for training, are therefore highly desirable.
Tuning-free multi-coil compressed sensing MRI with Parallel Variable Density Approximate Message Passing (P-VDAMP)
To our knowledge, P-VDAMP is the first algorithm for multi-coil MRI data that obeys a state evolution with accurately tracked parameters.
Approximate Message Passing with a Colored Aliasing Model for Variable Density Fourier Sampled Images
Central to AMP is its "state evolution", which guarantees that the difference between the current estimate and ground truth (the "aliasing") at every iteration obeys a Gaussian distribution that can be fully characterized by a scalar.
An Approximate Message Passing Algorithm for Rapid Parameter-Free Compressed Sensing MRI
In response we present an algorithm based on Orthogonal AMP constructed specifically for variable density partial Fourier sensing matrices.
