Quantitative Magnetic Resonance Imaging by Nonlinear Inversion of the Bloch Equations
Nick Scholand, Xiaoqing Wang, Volkert Roeloffs +2
Purpose: Development of a generic model-based reconstruction framework for multi-parametric quantitative MRI that can be used with data from different pulse sequences. Methods: Gen…
Free-Breathing Myocardial T1 Mapping using Inversion-Recovery Radial FLASH and Motion-Resolved Model-Based Reconstruction
Xiaoqing Wang, Sebastian Rosenzweig, Volkert Roeloffs +7
Purpose: To develop a free-breathing myocardial T1 mapping technique using inversion-recovery (IR) radial fast low-angle shot (FLASH) and calibrationless motion-resolved model-base…
Physics-based Reconstruction Methods for Magnetic Resonance Imaging
Xiaoqing Wang, Zhengguo Tan, Nick Scholand +2
Conventional Magnetic Resonance Imaging (MRI) is hampered by long scan times and only qualitative image contrasts that prohibit a direct comparison between different systems. To ad…
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…
