@article{Shimron2019COREPINC, title={CORE‐PI: Non‐iterative convolution‐based reconstruction for parallel MRI in the wavelet domain}, author={Efrat Shimron and Andrew G. Webb and Haim Azhari}, journal={Medical Physics}, year={2019}, volume={46}, pages={199–214} }
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…

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.
