background: increasing frame rate is a challenging issue for better interpretation of medical images and diagnosis based on tracking the small transient motions of myocardium and valves in real time visualization. methods: in this paper, manifold learning algorithm is applied to extract the nonlinear embedded information about echocardiography images from the consecutive images in two dimension...
Introduction: Echocardiography is a diagnostic test in that ultrasound waves are used for producing images of the heart muscle and valves. Echocardiography provides a series of useful information about the heart and its function for treatment purpose. It is especially useful for assessing valvular heart disease. Although it has no known side effect, but similar to any other medical procedure, i...
Nowadays transcatheter closure has become the standard treatment for an atrial septal defect (ASD). Since morphologic variation of ASD is common, imaging modalities with high diagnostic ability continue to be required. Meanwhile, experts are required to visualize high quality images with advanced imaging modalities. Echocardiography plays a pivotal role in patient selection for treatment, recen...
AIMS We analyzed the usefulness of quantitative intravenous myocardial contrast echocardiography to study microvasculature perfusion after infarction in comparison with intracoronary myocardial contrast echocardiography. METHODS AND RESULTS Thirty-two patients with a first ST elevation myocardial infarction, single-vessel disease and an open artery (TIMI 3) were studied before discharge. Myoc...
Objective- to determine the range of systolic times intervals using Pulsed-wave Doppler and m-mode echocardiography in normal, healthy Great Dane dogs. Design- Descriptive study. Animals- Thirty healthy Great Dane dogs. Procedures- This study examined 30 clinically healthy Great Dane dogs by the twodimensional, M-mode and Pulsed-wave Doppler echocardiography. The dogs were awake and unsedated. ...
Introduction: Cardiovascular diseases are one of the leading causes of mortality in today’s industrial world. Occlusion of left atrial appendage (LAA) using the manufactured devices is a growing trend. The objective of this study was to develop a computer-aided diagnosis system for the identification of LAA in echocardiographic images. Method: The data used in this descriptive analytical study ...
