Resolution and accuracy in two dimensional echocardiography

The American Journal of Cardiology, 1981
The resolution and accuracy of commercially available two dimensional echocardiographic systems were tested by imaging two types of in vitro test objects. One consisted of a series of fine parallel threads spaced at known intervals and the other was a tissue phantom in which a series of holes of known size had been cut.

Reproducibility of quantitative two-dimensional echocardiography

American Heart Journal, 1988
In order to assess reproducibility of quantitative planimetry, three physicians trained in two-dimensional echocardiography performed five successive studies on one another over 2 weeks (30 total studies). Then each physician traced each study (90 total tracings) for left ventricular and atrial volumes and ejection fraction by means of a modification ...

Textbook of two-dimensional echocardiography

International Journal of Cardiology, 1984
ABSTRACT This clearly and concisely written, abundantly and appropriately illustrated, and handsomely bound volume deserves its title: Textbook of Two-Dimensional Echocardiography. Although it is a multiauthored text, there is a unity of writing style and content from chapter to chapter.

Uses and abuses of two-dimensional echocardiography

International Journal of Cardiology, 1982
Abstract The rapid proliferation of new cardiac diagnostic methods during the past decade has inevitably resulted in a number of problems and uncertainties in the assimilation and clinical application of these techniques. Two-dimensional echocardiography is an important example of such a new method which because of its wide applicability, safety and ...

Chest trauma: Evaluation by two-dimensional echocardiography

American Heart Journal, 1987
Patients with either blunt or penetrating chest injuries may develop a variety of cardiac complications. The studies of 76 patients with suspected cardiac injury obtained over a 30-month period were reviewed in order to determine how frequently and in what manner two-dimensional echocardiography (2DE) is of value in the assessment of such patients ...

Anatomical validation of two‐dimensional echocardiography in the horse

Equine Veterinary Journal, 1990
Summary This study was performed on 15 horses to validate the cardiac anatomy as imaged with two dimensional echocardiography (2DE) and to determine the accuracy of intracardiac measurements. 2DE images were recorded in five horses in life with a Diasonics DRF100 ultrasound system and a 3.5 MHz transducer in ...

Real time computerization of two-dimensional echocardiography

American Heart Journal, 1981
A computerized system was developed for real time acquisition, enhanced processing, analysis, and display of cross-sectional images of the left ventricle derived by two-dimensional echocardiography (2DE). The new methodology couples a standard medical imaging computer system to the video output of any current 2DE unit, uses a 128 x 128 or 64 x 64 ...

Digital two-dimensional echocardiography

1985
Over the past two decades, echocardiography has emerged as an essential diagnostic tool in clinical cardiology. This is related to the fact that it is entirely noninvasive, can be readily performed at the bedside, and can provide accurate and reproducible information at no known risk to the patient. M-mode echocardiography was initially used to provide
