PURPOSE To develop and test a novel parameter-free non-iterative wavelet domain method for reconstruction of undersampled multicoil MR data. THEORY AND METHODS A linear parallel MRI method that operates in the Stationary Wavelet Transform (SWT) domain is proposed. The method is coined COnvolution-based REconstruction for Parallel MRI (CORE-PI). This method computes the SWT of the unknown MR image directly from subsampled k-space measurements, without modifying the RF excitation pulse. It then…

A dictionary‐based graph‐cut algorithm for MRI reconstruction
TLDR
An efficient, discrete optimization formulation is proposed, which works not only on arbitrary Lp‐norm priors as some non‐convex CS methods do, but also on highly non‐ Convex truncated penalty functions, resulting in a specific type of edge‐preserving prior.
Magnetic Resonance Imaging Based on Wavelet Algorithm in the Diagnosis andTreatment ofTibialOsteomyelitisWound Infection
TLDR

A new approach to autocalibrating, coil‐by‐coil parallel imaging reconstruction, is presented, a generalized reconstruction framework based on self‐consistency that can accurately reconstruct images from arbitrary k‐space sampling patterns.
A Fast Wavelet-Based Reconstruction Method for Magnetic Resonance Imaging
TLDR
This work exploits the fact that wavelets can represent magnetic resonance images well, with relatively few coefficients, to improve magnetic resonance imaging (MRI) reconstructions from undersampled data with arbitrary k-space trajectories and proposes a variant that combines recent improvements in convex optimization and that can be tuned to a given specific k- space trajectory.

TLDR
Using the proposed method, SENSE becomes practical with nonstandard k‐space trajectories, enabling considerable scan time reduction with respect to mere gradient encoding, and the in vivo feasibility of non‐Cartesian SENSE imaging with iterative reconstruction is demonstrated.

Practical incoherent undersampling schemes are developed and analyzed by means of their aliasing interference and demonstrate improved spatial resolution and accelerated acquisition for multislice fast spin‐echo brain imaging and 3D contrast enhanced angiography.
SENSE: Sensitivity encoding for fast MRI
TLDR
The problem of image reconstruction from sensitivity encoded data is formulated in a general fashion and solved for arbitrary coil configurations and k‐space sampling patterns and special attention is given to the currently most practical case, namely, sampling a common Cartesian grid with reduced density.
