Tissue response to mechanical vibrations for "sonoelasticity imaging".
The goal of "sonoelasticity imaging" is to differentiate between normal soft tissues and hard lesions. This is done by measuring and then displaying the ultrasound Doppler spectrum of regions withinExpand

Imaging of the elastic properties of tissue--a review.
In this paper, we survey some of the previous work done in the related biomechanics, and we review measurement techniques from the 1950s to the 1980s. Expand

Analysis of 1.4 GHz Radiometric measurements from Skylab
Abstract Results from the 1.4 GHz, S-194, microwave radiometer located on the SKYLAB satellite are presented. The objective of the investigation is to establish the degree to which quantitativeExpand

In-vivo measurements of ultrasound attenuation in normal or diseased liver.
Ultrasonic attenuation coefficients of liver have been derived from echoes received by a modified commercial B-scan imaging instrument. Values have been measured from selected regions within liverExpand

Color Doppler US in the evaluation of acute scrotal disease.
Twenty-seven patients presented with painful acute scrotal swelling. After a clinical impression was established, all patients underwent diagnostic imaging with color Doppler ultrasound (US). SevenExpand

Comparison of techniques for in vivo attenuation measurements
The attenuation of an ultrasound pulse within tissue can be estimated from either the amplitude decay or the frequency downshift of returning echoes. Expand

Sono-Elasticity: Medical Elasticity Images Derived from Ultrasound Signals in Mechanically Vibrated Targets
Cancers of the prostate have traditionally been detected by digital palpation which identifies increased stiffness (modulus of elasticity, hardness) of the abnormal tissue. Gray-scale ultrasound isExpand

"Sonoelasticity" images derived from ultrasound signals in mechanically vibrated tissues.
A method has been developed for detecting and imaging the relative "stiffness," or elasticity of tissues. Externally applied vibration at low frequencies (10-1000 Hz) is used to induce oscillationsExpand

Sonographic measurement of diaphragmatic motion after coronary artery bypass surgery.
Forty-eight patients were prospectively evaluated following coronary artery bypass grafting (CABG) in order to determine values for diaphragmatic mobility by sonography, to compare diaphragmaticExpand
