Review ArticleOpen accessEvery word in the titleSegmentation Methods of Echocardiography Images for Left Ventricle Boundary DetectionSamaneh Mazaheri, Rahmita Wirza, Puteri Suhaiza Sulaiman et al.Due to acoustic interferences and artifacts which are inherent in echocardiography images, automatic segmentation of anatomical structures in cardiac ultrasound images is a real challenge. This paper surveys state-of-the-art researches on echocardiography data segmentation methods, concentrating on methods techniques developed for clinical data. We present a classification of methodologies for echocardiography image segmentation. By choosing ten recent papers which have … …Journal of Computer Science, Vol. 11, Issue 9 · 6 Dec 2015 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCAVITY SEGMENTATION AND STROKE VOLUME MEASUREMENT METHODS FROM ECHOCARDIOGRAPHIC IMAGES: REVIEWAnas A. Abboud, Rahmita Wirza Rahmat, Suhaini Bin Kadiman et al.The complexity and criticality of heart disease diagnosis and treatment have frequently attracted the attention of researchers to develop approaches that can handle accurate clinical assessments. One of these complexities is measuring the Right Ventricle stroke volume. Therefore, different cardiac imaging techniques have been developed to help specialists in their regular clinical work and in the operating theatre to assist … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,410 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAutomatic Detection of the End-Diastolic and End-Systolic from 4D Echocardiographic ImagesAnas A. Abboud, Rahmita Wirza Rahmat, Suhaini Bin Kadiman et al.Accurate detection of the End-Diastolic (ED) and End-Systolic (ES) frames of a cardiac cycle are significant factors that may affect the accuracy of abnormality assessment of a ventricle. This process is a routine step of the ventricle assessment procedure as most of the time in clinical reports many parameters are measured in these two frames to help in diagnosing and … …Journal of Computer Science, Vol. 11, Issue 1 · 25 Aug 2014 · 8,500 accessesView PDFCite
Research ArticleOpen accessIn the abstractEchocardiographic Pulmonary to Left Atrial Ratio in Dogs (ePLAR): A Differential Marker of Pre- and Postcapillary Pulmonary HypertensionDmitrij Oleynikov, Ma YiPulmonary Hypertension (PH) in dogs is a complicated syndrome that could be primary, due to idiopathic or genetic causes, or secondary due to pulmonary disease, pulmonary thromboembolism, heartworm disease, heart failure. Due to the inability of the routine use of right heart catheterization in veterinary patients, there is a lack of differential criteria between PH forms. This study was performed … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 1 · 17 Feb 2022 · 6,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerinatal Cardiovascular Evaluation in Dorper Sheep Echocardiographic Description and Behavior of the Heart Rate Variability on the FieldAmanda Sarita Cruz Aleixo, Mayra de Castro Ferreira Lima, Ana Luísa Holanda de Albuquerque et al.The heart is innervated by the autonomic nervous system, with a predominance of sympathetic and parasympathetic activity associated, respectively, with increases and decreases in the heart rate, as illustrated by the Heart Rate Variability (HRV). Pregnancy induces significant changes in the maternal cardiovascular and hemodynamic systems. This study aimed at evaluating changes in the clinical and echocardiographic parameters of pregnant … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 3 Nov 2021 · 6,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Medical Image SegmentationNandagopalan Shanmugam, Adiga B. Suryanarayana, Sudarshan TSB et al.Problem statement: Segmentation is a vital aspect of medical imaging. It aids in the visualization of medical data and diagnostics of various diseases. Ultrasound image segmentation, in particular echocardiographic image segmentation, is required to identify the regions of interest such as Left Ventricle (LV) and other cardiac cavities. Existing methods do not address the drawbacks of speed and quality of … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbdominal and Thoracic Aortic Aneurysm ModelingMona Abdolrazaghi, Mehdi NavidBakhsh, Kamran HassaniModeling is a beneficial tool for understanding cardiovascular system functioning and pathophysiology of the system. The present study is concerned with left ventricle Pressure-Volume diagrams obtained by modeling of aortic aneurysms using the cardiovascular electronic system. In addition, these graphs were compared with a normal condition. The electrical circuit of the cardiovascular system consists of 42 segments including the main … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractToll-Like Receptor (TLR) 2 and TLR4 Gene Expression in Canine HeartA. Linde, F. Blecha, T. MelgarejoToll-like receptors (TLRs) are archetypal pattern recognition receptors of immediate importance for an efficacious innate immune response. TLRs exhibit marked differential tissue activity and their levels within a discrete cell type can be highly dynamic. Of 13 known mammalian paralogues, three TLRs have been identified in the dog. Although cardiac TLR expression has been reported in other species, this study … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 6,921 accessesView PDFCite
