Compressed Sensing MRI Reconstruction Regularized by VAEs with Structured Image Covariance
Margaret Duff, Ivor J. A. Simpson, Matthias J. Ehrhardt +1
Objective: This paper investigates how generative models, trained on ground-truth images, can be used \changes{as} priors for inverse problems, penalizing reconstructions far from…
Flexible Amortized Variational Inference in qBOLD MRI
Ivor J. A. Simpson, Ashley McManamon, Balázs Örzsik +5
Streamlined qBOLD acquisitions enable experimentally straightforward observations of brain oxygen metabolism. maps are easily inferred; however, the Oxygen extraction…
Learning Structured Gaussians to Approximate Deep Ensembles
Ivor J. A. Simpson, Sara Vicente, Neill D. F. Campbell
This paper proposes using a sparse-structured multivariate Gaussian to provide a closed-form approximator for the output of probabilistic ensemble models used for dense image predi…
