Computational time-of-flight diffuse optical tomography
Ashley Lyons, Francesco Tonolini, Alessandro Boccolini +4
Imaging through a strongly diffusive medium remains an outstanding challenge in particular in association with applications in biological and medical imaging. Here we propose a met…
Greedy Approximate Projection for Magnetic Resonance Fingerprinting with Partial Volumes
Roberto Duarte, Audrey Repetti, Pedro A. Gómez +2
In quantitative Magnetic Resonance Imaging, traditional methods suffer from the so-called Partial Volume Effect (PVE) due to spatial resolution limitations. As a consequence of PVE…
Scalable Bayesian uncertainty quantification in imaging inverse problems via convex optimization
Audrey Repetti, Marcelo Pereyra, Yves Wiaux
We propose a Bayesian uncertainty quantification method for large-scale imaging inverse problems. Our method applies to all Bayesian models that are log-concave, where maximum-a-po…
Fast Fiber Orientation Estimation in Diffusion MRI from kq-Space Sampling and Anatomical Priors
Marica Pesce, Audrey Repetti, Anna Auría +3
High spatio-angular resolution diffusion MRI (dMRI) has been shown to provide accurate identification of complex neuronal fiber configurations, albeit, at the cost of long acquisit…
Sparse interferometric Stokes imaging under polarization constraint (Polarized SARA)
Jasleen Birdi, Audrey Repetti, Yves Wiaux
We develop a novel algorithm for sparse Stokes parameters imaging in radio interferometry under the polarization constraint. The latter is a physical non-linear relation between th…
