Deep variational network for rapid 4D flow MRI reconstruction
TL;DR: A deep variational network is developed to permit high-fidelity image reconstruction in a matter of seconds, allowing integration of 4D flow MRI into clinical workflows and evaluating its performance on clinical aortic flow data.
Proceedings ArticleDOI
Ultrasound Aberration Correction based on Local Speed-of-Sound Map Estimation
TL;DR: This paper demonstrates a direct delay correction approach for US beamforming, by leveraging 2D spatial SoS distribution estimates from plane-wave imaging and proves that resolutions close to the wavelength limit can be achieved using the proposed local SoS-adaptive beamforming.
Journal ArticleDOI
Speed-of-Sound Imaging using Diverging Waves
TL;DR: Diverging waves (DW) is proposed for SoS imaging and its effects on the key step of displacement tracking in the SoS reconstruction pipeline, comparatively between PW and DW on a synthetic example, and the parameterization sensitivity of both approaches is presented on a set of simulated phantoms.
Journal ArticleDOI
Determinants of myocardial function characterized by CMR-derived strain parameters in left ventricular non-compaction cardiomyopathy

TL;DR: CMR deformation indices are reduced in patients with LVNC especially in affected midventricular and apical slices, and the impairment of all strain and twist parameters correlates well with the extent of non-compacted myocardium.
Book ChapterDOI
Deep Variational Networks with Exponential Weighting for Learning Computed Tomography
TL;DR: In this article, a network architecture that performs filtering jointly in both sinogram and spatial domains is proposed to learn an inverse mapping in an end-to-end fashion via unrolling optimization iterations of a prototypical reconstruction algorithm.
