Generation of Synthetic Rat Brain MRI scans with a 3D Enhanced Alpha-GAN
André Ferreira, Ricardo Magalhães, Sébastien Mériaux +1
Translational brain research using Magnetic Resonance Imaging (MRI) is becoming increasingly popular as animal models are an essential part of scientific studies and more ultra-hig…
Variable density sampling based on physically plausible gradient waveform. Application to 3D MRI angiography
Nicolas Chauffert, Pierre Weiss, Marianne Boucher +2
Performing k-space variable density sampling is a popular way of reducing scanning time in Magnetic Resonance Imaging (MRI). Unfortunately, given a sampling trajectory, it is not c…
Spatio-temporal wavelet regularization for parallel MRI reconstruction: application to functional MRI
Lotfi Chaari, Sébastien Mériaux, Jean-Christophe Pesquet +1
Parallel MRI is a fast imaging technique that enables the acquisition of highly resolved images in space or/and in time. The performance of parallel imaging strongly depends on the…
4D Wavelet-Based Regularization for Parallel MRI Reconstruction: Impact on Subject and Group-Levels Statistical Sensitivity in fMRI
Lotfi Chaari, Sébastien Mériaux, Solveig Badillo +2
Parallel MRI is a fast imaging technique that enables the acquisition of highly resolved images in space. It relies on -space undersampling and multiple receiver coils with comp…
