Harmonization of diffusion MRI datasets with adaptive dictionary learning

Diffusion weighted magnetic resonance imaging is a noninvasive imaging technique which can indirectly infer the microstructure of tissues and provide metrics which are subject to normal variability across subjects. Potentially abnormal values or …

Restoration and characterization of diffusion MRI data

Diffusion magnetic resonance imaging (dMRI) is an imaging technique to obtain information about the microstructural properties of tissues non-invasively, such as white matter in the human brain. The properties of the dMRI signal can be used to …

Non Local Spatial and Angular Matching: Enabling higher spatial resolution diffusion MRI datasets through adaptive denoising

Diffusion magnetic resonance imaging datasets suffer from low Signal-to-Noise Ratio, especially at high b-values. Acquiring data at high b-values contains relevant information and is now of great interest for microstructural and connectomics studies. …
