Conference Annu Int Conf IEEE Eng Med Biol Soc · July 2020 Over the last decade, convolutional neural networks (CNNs) have emerged as the leading algorithms in image classification and segmentation. Recent publication of large medical imaging databases have accelerated their use in the biomedical arena. While trai ... Full text Link to item Cite

Interpreting edge information for improved endocardium delineation in echocardiograms

Conference 9th IEEE International Symposium on Biomedical Imaging (ISBI) Successful segmentation of the left ventricle in echocardiograms relies on strong edge responses to ensure that segmentation methods converge to the endocardial boundary. However, segmentation methods that do not interpret edge responses using local shape ... Full text Cite

Modified Hough transform for left ventricle myocardium segmentation in 3-D echocardiogram images

Conference 9th IEEE International Symposium on Biomedical Imaging (ISBI) Segmentation of the left ventricular myocardium from 3D echocardiograms is complicated by speckle, artifact, and complex anatomy. Typical segmentation methods benefit from accurate initialization. We propose a two-step Hough transform to find an annular ap ... Full text Cite

Learning optical flow propagation strategies using random forests for fast segmentation in dynamic 2D & 3D echocardiography

Conference Fast segmentation of the left ventricular (LV) myocardium in 3D+time echocardiographic sequences can provide quantitative data of heart function that can aid in clinical diagnosis and disease assessment. We present an algorithm for automatic segmentation o ... Cite

Comparison of native versus ablation-induced scar on left atrial magnetic resonance imaging

Conference 35th Heart Rhythm Society Introduction: Previous studies have demonstrated that the extent of left atrial (LA) myocardial native and ablation-induced scar is associated with post-ablation atrial fibrillation (AF) recurrence. However methodologies to distinguish native versus ablati ... Cite

Dissecting inflammatory and chemotactic pathways in Familial Mediterranean Fever

Conference Background: Familial Mediterrean fever (FMF) is a heritable autoinflammatory disease characterized by substantial neutrophil influx at sites of serosal and synovial involvement. Inflammatory attacks are usually prevented by prophylaxis with colchicine, a m ... Cite
