Intravascular ultrasound assessment of lumen size and wall morphology in normal subjects and patients with coronary artery disease.
Steven E. Nissen,John C. Gurley,Cindy L. Grines,David C. Booth,Rick R. McClure,Martin R. Berk,Charles Fischer,Anthony N. DeMaria +7 more
TL;DR: These data establish that intravascular ultrasound is feasible and safe and yields luminal measurements that correlate generally with angiography, and differences between angiographic and ultrasonic measures of lumen size in eccentric vessels probably reflect the dissimilar perspectives of tomographic and silhouette imaging techniques.
PatentDOI
Ultra-thin acoustic transducer and balloon catheter using same in imaging array subassembly
TL;DR: An array of miniature ultrasound crystals mounted on preassembled subassembly which is, in turn, mounted on a small lumen catheter provides dimensional and other quantitative information relating to arterial wall geometry and character at disease or obstruction sites as mentioned in this paper.
Journal ArticleDOI
Application of a new phased-array ultrasound imaging catheter in the assessment of vascular dimensions. In vivo comparison to cineangiography.
Steven E. Nissen,Cindy L. Grines,John C. Gurley,Kevin L. Sublett,David Haynie,Cheryl Diaz,David C. Booth,Anthony N. DeMaria +7 more
TL;DR: Data demonstrate that intravascular ultrasound is an accurate and reproducible method for measurement of vascular diameter and cross-sectional area in vivo and is capable of accurately identifying and quantifying segmental deformation of vascular dimensions produced by either stenoses or balloon dilation.

Left Ventricular Wall Thickness Measured by Ultrasound
TL;DR: A new technique for measuring thickness of the left ventricular wall utilizes pulsed reflected ultrasound and can be performed at the bedside in a matter of minutes without discomfort or risk.
Journal ArticleDOI
Limitations on directional patterns of phase-compensated circular arrays
TL;DR: In this paper, the principal design parameters of phase compensated circular arrays with a view to the synthesis of diametricplane directional patterns having low side-lobes were studied, and it was shown that a maximum inter-element spacing exists, which if exceeded results in a rapid increase of sde-lobe level.

Ultrasonic tomography of the heart: An intracardiac scan method
TL;DR: In animal experiments, such structures as the right and left atrial walls, interatrial septums and right ventricles and aortas could be identified, suggesting the value of the method of diagnosis in clinical practice.
