Journal ArticleDOI
Intravascular ultrasound image segmentation: a three-dimensional fast-marching method based on gray level distributions
Marie-Hélène Roy Cardinal,Jean Meunier,Gilles Soulez,Roch L. Maurice,Eric Therasse,Guy Cloutier +5 more
TL;DR: A new three-dimensional IVUS segmentation model, that is based on the fast-marching method and uses gray level probability density functions (PDFs) of the vessel wall structures, was developed and demonstrated the potential of gray level PDF and fast- marching methods in 3-D IVUS image processing.
Journal ArticleDOI
Assessment of Carotid Artery Plaque Components With Machine Learning Classification Using Homodyned-K Parametric Maps and Elastograms
TL;DR: The added value of combining different features computed from a single US acquisition with machine learning to characterize carotid artery plaques is shown.
Journal ArticleDOI
Endovascular Shear Strain Elastography for the Detection and Characterization of the Severity of Atherosclerotic Plaques: In Vitro Validation and In Vivo Evaluation
Younes Majdouline,Jacques Ohayon,Zahra Keshavarz-Motamed,Marie Hélène Roy Cardinal,Damien Garcia,Louise Allard,Sophie Lerouge,Sophie Lerouge,Frédéric Arsenault,Gilles Soulez,Guy Cloutier +10 more
TL;DR: The feasibility of using SSE to highlight atherosclerotic plaque vulnerability characteristics is indicated, and the Lagrangian speckle model estimator (LSME) elasticity imaging method was further developed to estimate shear strain elasticity (SSE).
Journal ArticleDOI
Carotid Artery Plaque Vulnerability Assessment Using Noninvasive Ultrasound Elastography: Validation With MRI.
Marie-Hélène Roy Cardinal,Maarten H. G. Heusinkveld,Maarten H. G. Heusinkveld,Zhao Qin,Richard G.P. Lopata,Cyrille Naim,Gilles Soulez,Guy Cloutier +7 more
TL;DR: The imaging parameters cumulated axial translation and the ratio of cumulation axial strain to cumulatedAxial translation, as computed using NIVE, were able to discriminate vulnerable carotid artery plaques characterized by MRI from nonvulnerable carotids.
Journal ArticleDOI
Fast‐marching segmentation of three‐dimensional intravascular ultrasound images: A pre‐ and post‐intervention study
TL;DR: This new IVUS segmentation method provides accurate results that correspond well to the experts' manually traced contours, but requires much less manual interactions and is faster.
