Journal ArticleDOI
Computer-aided quantification of contrast agent spatial distribution within atherosclerotic plaque in contrast-enhanced ultrasound image sequences
TL;DR: A computer-aided method is proposed for objective and convenient quantification of contrast agent spatial distribution within plaques in CEUS image sequences including cardiac cycle retrieval and sub-sequence selection, temporal mean image segmentation, and texture feature extraction.
Journal ArticleDOI
Quantification of carotid plaque elasticity and intraplaque neovascularization using contrast-enhanced ultrasound and image registration-based elastography
TL;DR: An ultrasound elastography technique based on registration of CEUS sequential images is developed and used for direct comparison between IPN and plaque elasticity and might be helpful for evaluation of carotid plaque vulnerability and for plaque risk stratification.
Proceedings ArticleDOI
Ultrasound image segmentation based on multi-scale fuzzy c-means and particle swarm optimization
TL;DR: Results demonstrate that the MsFCM-PSO can provide an accurate tool for ultrasound image segmentation and outperformed the traditional fuzzy c-means methods by 39.6% and 13.6%, in terms of the Pratt's figure of merit and segmentation accuracy, respectively.
Proceedings ArticleDOI
Contrast-enhanced ultrasound image segmentation of atherosclerotic plaques using spatial-temporal analysis and snakes
TL;DR: Wang et al. as discussed by the authors used spatial correlation of time intensity curves to capture detailed information from spatial-temporal neighborhoods of plaques and detect initial contours of the plaques, and then the speckle reducing anisotropic diffusion is adopted to modify the edge map of the gradient vector flow snake, and the initial contour are deformed using the modified snake and converged to refined contours.
