Sparse Registration for Three-Dimensional Stress Echocardiography

IEEE Transactions on Medical Imaging, 2008
Three-dimensional (3-D) stress echocardiography is a novel technique for diagnosing cardiac dysfunction. It involves evaluating wall motion of the left ventricle, by visually analyzing ultrasound images obtained in rest and in different stages of stress. Since the acquisitions are performed minutes apart, variabilities may exist in the visualized cross-

Three‐Dimensional Transesophageal Echocardiography of Aortic Atherosclerosis

Echocardiography, 2012
Mini‐AbstractWe present a 75‐year‐old woman with symptomatic severe aortic stenosis who underwent transesophageal echocardiography (TOE) as part of the routine examinations before scheduling transcatheter aortic valve implantation. The examination identified, in addition to severe calcific aortic stenosis, intimal thickening of the ascending aorta ...

Three-Dimensional Echocardiography in Clinical Practice

2010
The heart has a complex anatomy and it is in constant motion. Conventional two-dimensional (2D) echocardiography can only provide partial information about the spatial and temporal relationship of cardiac structures during the cardiac cycle (Fig. 4.1). Furthermore, conventional 2D echocardiography requires a difficult mental process by the operator to ...

Dynamic Three-Dimensional Echocardiography

Japanese Journal of Applied Physics, 2000
Conventional three-dimensional (3D) ultrasound imaging equipment for diagnosis requires much time to reconstruct 3D images or fix the view point for observing the 3D image. Thus, it is inconvenient for cardiac diagnosis. In this paper, we propose a new dynamic 3D echocardiography system.

Three-dimensional echocardiography.

American journal of cardiac imaging, 1993
Lack of spatial registration of imaging transducers is a major technical limitation of two-dimensional (2-D) echocardiography. Volume scanning of the heart, or three-dimensional (3-D) echocardiography, is achieved by using a 3-D spatial registration device with a conventional 2-D scanner, or by using a high speed, phased-array real-time scanner. Three-

Three‐Dimensional Echocardiography in Congenital Heart Disease

Echocardiography, 2008
Complex intracardiac anatomy and spatial relationships are inherent to congenital heart defects (CHDs). Recognition of the limitations of two‐dimensional echocardiography has stimulated clinical interest in three‐dimensional imaging. The current review examines contemporary studies in the following areas where three‐dimensional echocardiography has ...
