Clinical Application of Three-Dimensional Echocardiography

Progress in Cardiovascular Diseases, 2014
Echocardiography is one of the most valuable diagnostic tools in cardiology. Technological advances in ultrasound, computer and electronics enables three-dimensional (3-D) imaging to be a clinically viable modality which has significant impact on diagnosis, management and interventional procedures.

Three‐Dimensional Echocardiography of the Atrial Septum

Echocardiography, 2001
This article details the important contribution of three‐dimensional echocardiography for catheterization device closure of secundum atrial septal defects. Aspects presented include three‐dimensional echocardiographic application in preselection of patients and in selection of the type and size of the atrial septal occluder devices.

Three-dimensional and four-dimensional echocardiography

Ultrasound in Medicine & Biology, 1994
Since its introduction in 1974, 3-D reconstruction of the heart has undergone significant technological refinements in image acquisition, processing and display techniques. Image acquisition for transthoracic 3-D reconstruction utilizes the parasternal or apical windows, or combinations of the two.

Three‐Dimensional Echocardiography of Intracardiac Masses

Echocardiography, 2004
We describe two cases in which three‐dimensional echocardiography provided unique anatomical data. This information enhanced the diagnostic power of two‐dimensional echocardiography by improving confidence in interpretation and by providing distinctive spatial insights.

Three-dimensional echocardiography: Techniques and applications

The American Journal of Cardiology, 1992
Current echocardiographic devices provide only 2-dimensional views of the heart. To appreciate 3-dimensional structural relations, therefore, requires mental reconstruction of 2-dimensional views by an experienced observer. Our ability to answer new questions about the heart could be increased if 2-dimensional images could be combined to display 3 ...

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-
