A fast 4D B-spline framework for model-based reconstruction and regularization in vector flow imaging
Grønli, Thomas; Wigen, Morten Smedsrud; Segers, Patrick; Løvstakken, Lasse (Journal article; Peer reviewed, 2018)A generic framework for model-based regularization and reconstruction is described, with applications in a wide range of noisy measurement scenarios. The framework employs automatic differentiation and stochastic gradient ... -
Effect of Ultrafast Imaging on Shear Wave Visualization and Characterization: An Experimental and Computational Study in a Pediatric Ventricular Model
Caenen, Annette; Pernot, Mathieu; Ekroll, Ingvild Kinn; Shcherbakova, Darya; Mertens, Luc; Swillens, Abigail Emily; Segers, Patrick (Journal article; Peer reviewed, 2017)Plane wave imaging in Shear Wave Elastography (SWE) captures shear wave propagation in real-time at ultrafast frame rates. To assess the capability of this technique in accurately visualizing the underlying shear wave ... -
Right Ventricular Flow Dynamics in Dilated Right Ventricles: Energy Loss Estimation Based on Blood Speckle Tracking Echocardiography-A Pilot Study in Children
Mawad, Wadi; Løvstakken, Lasse; Fadnes, Solveig; Grønli, Thomas; Segers, Patrick; Mertens, Luc; Nyrnes, Siri Ann (Peer reviewed; Journal article, 2021)Using blood speckle tracking (BST) based on high-frame-rate echocardiography (HFRE), we compared right ventricle (RV) flow dynamics in children with atrial septal defects (ASDs) and repaired tetralogy of Fallot (rTOF). ...
