Example pipeline for undersampled (R=4) spiral image reconstruction with static B0 correction
- using MRIReco.jl, an MRI reconstruction framework written in Julia (Knopp and Grosser, MRM, 2021)
- and raw data (ISMRMRD, NIfTI) publicly available for download within the ETH Research Collection and described as a Data in Brief article.
This repository showcases an iterative image reconstruction (conjugate gradient SENSE) of undersampled high-resolution single-shot spiral fMRI data, including accelerated static B0 correction using pre-acquired and -processed B0 and sensitivity maps. The dataset is described in detail in a Data in Brief article. The spiral imaging results from that data, reconstructed with a similar algorithm (in Matlab), were published in our paper Advances in spiral fMRI: A high-resolution study with single-shot acquisition (Kasper et al., NeuroImage, 2022).
