Title
Learning How To Interpolate Fourier Data With Unknown Autoregressive Structure: An Ensemble-Based Approach
Abstract
It has been previously shown that the Fourier samples acquired in magnetic resonance imaging (MRI) experiments possess shift-invariant autoregressive structure, which has led to the emergence of various autocalibrated convolution-based image reconstruction approaches. Such approaches, which include GRAPPA, AC-LORAKS, RAKI, and LORAKI, each have their own relative strengths and weaknesses. In this work, we propose a novel ensemble-based approach that uses all of these approaches simultaneously as parallel building blocks within a larger data-adaptive reconstruction network. Results with real data suggest that the ensemble-based approach can synergistically utilize the strengths of each method, providing robust reconstruction performance without the need for interactive parameter tuning.
