3D Characterization of corneal deformation using ultrasound speckle tracking
The three-dimensional (3D) mechanical response of the cornea to intraocular pressure (IOP) elevation has not been previously reported. In this study, we use an ultrasound speckle tracking technique to measure the 3D displacements and strains within the central 5.5 mm of porcine corneas during the whole globe inflation. Inflation tests were performed on dextran-treated corneas (treated with a 10...
متن کاملAssessment of fetal myocardial deformation using speckle tracking techniques.
OBJECTIVE To report the current status of speckle tracking techniques in evaluation of fetal myocardial deformation. METHODS A variety of non-Doppler ultrasound methods are available using offline analysis of standard four-chamber and short axis views of the heart. RESULTS Most reports have used techniques developed for the measurement of strain and strain rate in the adult heart and produc...
متن کاملEndocardial surface area tracking for assessment of regional LV wall deformation with 3D speckle tracking imaging.
OBJECTIVES The aim of this experimental study was to validate area tracking by 3-dimensional (3D) speckle tracking imaging (STI) as a method to measure changes in regional left ventricular (LV) endocardial surface area with sonomicrometry and to assess the usefulness as a wall motion evaluation method compared with 1-dimensional strain parameters. BACKGROUND A 3D-STI allows for tracking a reg...

متن کاملUltrasound Speckle Tracking For Strain Estimation
This paper presents an alternative to Elastography by speckle tracking ultrasonic frames quantifying both motion and strain. We combine two similarity measures for varying echographic content including displacement processing, with interframe and trajectory performance measured on extensive synthetic and in vitro data.
