Strain Ratio as a Quantification Tool in Strain Imaging

myocardial strain and strain rate imaging: comparison between doppler derived strain imaging and speckle tracking echocardiography

Postprocessing Tool for 3D Strain Quantification from 3D Tagging Data

Introduction: 2D Tagging acquisition of the orbit during eye movement have proven to give new inside into the mechanical properties of orbital tissues,[1] and to be a valuable tool for investigating diseases etiologies.[2] 3D tagging acquisition have been shown to be feasible in a scantime short enough to enable motion reproducibility.[3] Nevertheless, the missing of an appropriate postprocessi...

Strain Quantification In Ultrasound Sequences

A novel methodology to quantify displacements and strain in musculoskeletal ultrasound sequences is presented. We extend the principles of 2D interframe displacements produced by our earlier work using hierarchical variable block size matching, to quantify displacement trajectories. We provide novel solutions for probe motion, quantification of objects moving in the 3D volume traversing the 2D ...

Quantification of Regional Myocardial Function following Acute Myocardial Infarction by Ultrasonic Strain Rate and Strain Imaging

Objectives: The rapid diagnosis and early risk stratification of patients presenting with acute myocardial infarction (AMI) is important. In experimental setting ultrasonic strain rate (SR) and strain (S) have been shown to identify changes in deformation predictive of ischemia. We sought to evaluate and compare regional myocardial function at “the risk zone” (ARZ) supplied by the culprit coron...
