Journal ArticleDOI
Elastography: A Quantitative Method for Imaging the Elasticity of Biological Tissues
TL;DR: Initial results of several phantom and excised animal tissue experiments are reported which demonstrate the ability of this technique to quantitatively image strain and elastic modulus distributions with good resolution, sensitivity and with diminished speckle.
Journal ArticleDOI
Elastography: elasticity imaging using ultrasound with application to muscle and breast in vivo.
TL;DR: A new elastography system based on a linear array transducer that is suitable for in vivo scanning is introduced and tissue mimicking phantom experiments and preliminary in vivo breast and muscle elastograms confirming the feasibility of performing elastographs in vivo are described.
Journal ArticleDOI
Methods for estimation of subsample time delays of digitized echo signals
TL;DR: It is demonstrated that reconstructive interpolation is unbiased and an iterative implementation of the reconstruction procedure is proposed that can reduce the Computation time significantly.
Journal ArticleDOI
Elastography: Ultrasonic imaging of tissue strain and elastic modulus in vivo
TL;DR: A literature review of a variety of methods for the estimation of tissue elasticity that have been reported in the literature in the past 15 years, and of data on the elastic properties of soft tissues.
Journal ArticleDOI
Reduction of Image Noise in Elastography
I. Céspedes,Jonathan Ophir +1 more
TL;DR: In this paper, the authors demonstrate that the noisy appearance of the elastograms is due to the nonstationary relationship between the pre- and postcompression signals that results in an artifactual modulation of the strain estimates by the amplitude variations of the envelope of the rf signal.
