In this paper, we model and explore brain development by learning a discriminative representation of the cortical brain data (T1 MRI) with a class-wise non-negative dictionary learning (NDDL) approach. For each class, the proposed approach performs data modeling by fir

Eva von Below,Wolfram Ebinger,Peter Lorenz,Ulrich Pramannn. Based on a measured system matrix, MPI reconstruction can be cast as an inverse problem that is commonly solved via regularized iterative optimization. Yet, hand-crafted regularization terms can elicit suboptimal performance. Here, we propose a novel MPI reconstruction “PP-MPI” based on a deep plu

We introduce “NPB-REC”, a non-parametric fully Bayesian framework for uncertainty assessment in MRI reconstruction from undersampled “k-space” data. We use Stochastic gradient Langevin dynamics (SGLD) during the training phase to characterize the posterior distribution of the netwo

Because current QSM techniques struggle to generate reliable QSM in clinical contexts, QSM clinical translation is greatly hindered. Recently, deep learning (DL) approaches for QSM reconstruction have shown impres

Recently, deep learning used for compressed sensing (CS) methods have been proposed to accelerate the acquisition by undersampling in the K-space and reconstruct images with neural networks. However, there are still some challenges remained: First, directly training network
