A simulation model of intraVascular ultraSound (IVUS)
(Universidad de Los Andes, 2009)
AUTOMATIC CORONARY WALL SEGMENTATION IN INTRAVASCULAR ULTRASOUND IMAGES USING BINARY MORPHOLOGICAL RECONSTRUCTION
(ELSEVIER SCIENCE INC, 2011)
Intravascular ultrasound (IVUS) image segmentation can provide more detailed vessel and plaque information, resulting in better diagnostics, evaluation and therapy planning. A novel automatic segmentation proposal is ...
Simultaneous assessment of coronary stenosis relevance with automated computed tomography angiography and intravascular ultrasound analyses and fractional flow reserve
(Wolters Kluwer Health, 2022-01)
Objectives: To assess the diagnostic performance of computed tomography angiography (CTA) and intravascular ultrasound (IVUS) derived minimum lumen areas (MLA) from the same lesions that correspond to an FFR ≤0.80. Methods ...
Atherosclerotic plaque characterization using plaque area variation in IVUS images during compression: a computational investigation
(SBEB - Sociedade Brasileira de Engenharia Biomédica, 2014-06-01)
INTRODUCTION: The rupture of atherosclerotic plaques causes millions of death yearly. It is known that the kind of predominant tissue is associated with its dangerousness. In addition, the mechanical properties of plaques ...
Automatic segmentation of the lumen region in intravascular images of the coronary artery
(Elsevier B.V., 2017-08-01)
Image assessment of the arterial system plays an important role in the diagnosis of cardiovascular diseases. The segmentation of the lumen and media-adventitia in intravascular (IVUS) images of the coronary artery is the ...
Evaluation of plaque composition by intravascular ultrasound ""virtual histology"": the impact of dense calcium on the measurement of necrotic tissue
(EUROPA EDITION, 2010)
Aims: We aimed to evaluate if the co-localisation of calcium and necrosis in intravascular ultrasound virtual histology (IVUS-VH) is due to artefact, and whether this effect can be mathematically estimated. Methods and ...
REALISTIC IVUS IMAGE GENERATION IN DIFFERENT INTRALUMINAL PRESSURES
(ELSEVIER SCIENCE INCNEW YORK, 2012)
Intravascular ultrasound (IVUS) phantoms are important to calibrate and evaluate many IVUS imaging processing tasks. However, phantom generation is never the primary focus of related works; hence, it cannot be well covered, ...
Improving Cardiac Phase Extraction in IVUS Studies by Integration of Gating Methods
(Institute of Electrical and Electronics Engineers, 2015-12)
Goal: Coronary intravascular ultrasound (IVUS) is a fundamental imaging technique for atherosclerotic plaque assessment. However, volume-based data retrieved from IVUS studies can be misleading due to the artifacts generated ...
TCT-72 Computational fractional flow reserve derived from three-dimensional intravascular ultrasound: a new algorithm of fusion between anatomy and physiology
(Elsevier Biomedical, 2017-10)
BACKGROUND: Fractionalflow reserve (FFR) and intravascular ultra-sound (IVUS) imaging, respectively, are considered as the ?goldstandard? for functional and anatomical assessments of angiographicintermediate stenoses. ...
