Joint T1 and T2 Mapping with Tiny Dictionaries and Subspace-Constrained Reconstruction
Volkert Roeloffs, Martin Uecker, Jens Frahm
Purpose: To develop a method that adaptively generates tiny dictionaries for joint T1-T2 mapping. Theory: This work breaks the bond between dictionary size and representation accur…
Frequency-modulated SSFP with radial sampling and subspace reconstruction: A time-efficient alternative to phase-cycled bSSFP
Volkert Roeloffs, Sebastian Rosenzweig, H. Christian M. Holme +2
Purpose: A novel subspace-based reconstruction method for frequency-modulated balanced steady-state free precession (fmSSFP) MRI is presented. In this work, suitable data acquisiti…
Simultaneous Multi-Slice MRI using Cartesian and Radial FLASH and Regularized Nonlinear Inversion: SMS-NLINV
Sebastian Rosenzweig, H. Christian M. Holme, Robin N. Wilke +3
Purpose: The development of a calibrationless parallel imaging method for accelerated simultaneous multi-slice (SMS) MRI based on Regularized Nonlinear Inversion (NLINV), evaluated…
Accelerated Computing in Magnetic Resonance Imaging -- Real-Time Imaging Using Non-Linear Inverse Reconstruction
Sebastian Schaetz, Dirk Voit, Jens Frahm +1
Purpose: To develop generic optimization strategies for image reconstruction using graphical processing units (GPUs) in magnetic resonance imaging (MRI) and to exemplarily report a…
Model-Based Iterative Reconstruction for Radial Fast Spin-Echo MRI
Kai Tobias Block, Martin Uecker, Jens Frahm
In radial fast spin-echo MRI, a set of overlapping spokes with an inconsistent T2 weighting is acquired, which results in an averaged image contrast when employing conventional ima…
Fast T2 Mapping with Improved Accuracy Using Undersampled Spin-echo MRI and Model-based Reconstructions with a Generating Function
Tilman J. Sumpf, Andreas Petrovic, Martin Uecker +2
A model-based reconstruction technique for accelerated T2 mapping with improved accuracy is proposed using undersampled Cartesian spin-echo MRI data. The technique employs an advan…
Aggregated motion estimation for real-time MRI reconstruction
Housen Li, Markus Haltmeier, Shuo Zhang +2
Real-time magnetic resonance imaging (MRI) methods generally shorten the measuring time by acquiring less data than needed according to the sampling theorem. In order to obtain a p…
