Three-dimensional echocardiography

2016
Abstract The advent of fully-sampled matrix array transthoracic transducers has enabled advanced digital processing and improved image formation algorithms and brought three-dimensional echocardiography (3DE) technology into clinical practice.

Artifacts in Three-Dimensional Transesophageal Echocardiography

Journal of the American Society of Echocardiography, 2014
Three-dimensional (3D) transesophageal echocardiography (TEE) is subject to the same types of artifacts encountered on two-dimensional TEE. However, when displayed in a 3D format, some of the artifacts appear more "realistic," whereas others are unique to image acquisition and postprocessing. Three-dimensional TEE is increasingly used in the setting of

Three‐Dimensional Echocardiography:

Echocardiography, 1999
Virtual reality (VR) is one of the latest developments in cardiac three‐dimensional (3‐D) ultrasound. A VR heart model linked to 3‐D echocardiographic image datasets provides the observers spatial information regarding a 3‐D image dataset and prevents the “lost in space effect” in difficult and relevant coupled diseases when integrated into 3‐D ...

Three-dimensional echocardiography.

Minerva cardioangiologica, 2005
Three-dimensional (3-D) echocardiography has been an important research goal ever since the introduction of two-dimensional (2-D) echocardiography. Most approaches towards 3-D echocardiography were off-line and based on the sequential rotational scanning and acquisition of multiple cross-sectional images together with external or internal reference ...

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.
