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: An Historical Perspective

Cardiology Clinics, 2007
Three-dimensional echocardiography (3DE) has made a dramatic transition from predominantly a research tool to a technology useful in everyday clinical practice. This article outlines the history of 3DE from its beginnings to the most current technology.

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‐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.

Real-time three-dimensional intracardiac echocardiography

Ultrasound in Medicine & Biology, 2001
Using catheter-mounted 2-D array transducers, we have obtained real-time 3-D intracardiac ultrasound (US) images. We have constructed several transducers with 64 channels inside a 12 French catheter lumen operating at 5 MHz. The transducer configuration may be side-scanning or beveled, with respect to the long axis of the catheter lumen.

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 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 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 ...

Three-dimensional stress echocardiography

2011
Over the last 25 years, stress echocardiography has become a widely used technique for diagnosis and risk stratification of patients with suspected or known coronary artery disease. However, relevant methodological limitations of conventional 2D stress echocardiography still exist.
