Internal displacement and strain imaging using ultrasonic speckle tracking
Previous ultrasound speckle tracking methods have been extended, permitting measurement of internal displacement and strain fields over a wide dynamic range of tissue motion. The markedly increasedExpand

Lateral displacement estimation using tissue incompressibility
Using the incompressibility property of soft tissue, lateral displacements can be reconstructed from axial strain measurements. Results of simulations and experiments on gelatin-based tissueExpand

Tissue elasticity reconstruction based on ultrasonic displacement and strain images
A method is presented to reconstruct the elastic modulus of soft tissue based on ultrasonic displacement and strain images. Incompressible and compressible media are considered separately. ProblemsExpand

Biophysical Bases of Elasticity Imaging
Elasticity imaging is based on two processes. The first is the evaluation of the mechanical response of a stressed tissue using imaging modalities, e.g. ultrasound, magnetic resonance imaging (MRI),Expand

Elasticity reconstructive imaging by means of stimulated echo MRI
A method is introduced to measure internal mechanical displacement and strain by means of MRI. Such measurements are needed to reconstruct an image of the elastic Young's modulus. A stimulated echoExpand

Strain rate imaging using two-dimensional speckle tracking
Strain rate images (SRI) of the beating heart have been proposed to identify non-contracting regions of myocardium. Initial attempts used spatial derivatives of tissue velocity (Doppler) signals.Expand

Displacement and strain imaging of coronary arteries with intraluminal ultrasound
Tissue elasticity can be estimated from displacement and strain images acquired under controlled deformation. We extend this approach for coronary arteries, deformed and imaged by an integratedExpand

Magnetic-resonance imaging techniques for detection of elasticity variation.
The relative success of manual palpation in the detection of breast cancer would suggest that a method for remote palpation resulting in a measurement of tissue elasticity could provide a diagnosticExpand

Theoretical analysis and verification of ultrasound displacement and strain imaging
Evaluation of internal displacement and strain distributions in tissue under externally applied forces is a necessary step in elasticity imaging. To obtain a quantitative image of the elasticExpand
