Left Ventricular Entropy as a Measure of Wall Motion Abnormalities in Echocardiography Images [PDF]

Iranian Journal of Electrical and Electronic Engineering
Cardiovascular diseases (CVD) are today a major cause of death globally that is diagnosed by measurement and quantification of left ventricle (LV) wall motion (WM) abnormality of the heart.

Bidirectional Recurrence for Cardiac Motion Tracking with Gaussian Process Latent Coding [PDF]

arXiv
Quantitative analysis of cardiac motion is crucial for assessing cardiac function. This analysis typically uses imaging modalities such as MRI and Echocardiograms that capture detailed image sequences throughout the heartbeat cycle. Previous methods predominantly focused on the analysis of image pairs lacking consideration of the motion dynamics and ...

Mechanically and Chemically Defined PEG Hydrogels Improve Reproducibility in Human Cardioid Development

Advanced Healthcare Materials, EarlyView.
Synthetic matrix metalloproteinase (MMP)‐degradable polyethylene glycol (PEG)‐based hydrogels are developed to investigate the influence of mechanical and biochemical cues on cardioid development. Matrix stiffness and cell adhesion motifs significantly regulate cardioid formation, chamber morphogenesis, contractile function, and cardioid transcriptome.

Echocardiography to Cardiac MRI View Transformation for Real-Time Blind Restoration [PDF]

arXiv
Echocardiography is the most widely used imaging to monitor cardiac functions, serving as the first line in early detection of myocardial ischemia and infarction. However, echocardiography often suffers from several artifacts including sensor noise, lack of contrast, severe saturation, and missing myocardial segments which severely limit its usage in ...

A Computer Vision Pipeline for Automated Determination of Cardiac Structure and Function and Detection of Disease by Two-Dimensional Echocardiography [PDF]

arXiv, 2017
Automated cardiac image interpretation has the potential to transform clinical practice in multiple ways including enabling low-cost serial assessment of cardiac function in the primary care and rural setting. We hypothesized that advances in computer vision could enable building a fully automated, scalable analysis pipeline for echocardiogram (echo ...
