A New Shear Wave Speed Estimation Method for Shear Wave Elasticity Imaging
In this paper, a novel method to estimate the shear wave speed is proposed. This method is a modified version of the lateral Time to Peak (TTP) method that estimates the induced shear wave speed. Lateral TTP algorithm finds the instance at which the maximum displacement is detected at each lateral location under examination at a certain depth. In the proposed algorithm each temporal displacemen...
متن کاملMeasuring shear-wave speed with point shear-wave elastography and MR elastography: a phantom study
OBJECTIVES To compare shear-wave speed (SWS) measured by ultrasound-based point shear-wave elastography (pSWE) and MR elastography (MRE) on phantoms with a known shear modulus, and to assess method validity and variability. METHODS 5 homogeneous phantoms of different stiffnesses were made. Shear modulus was measured by a rheometer, and this value was used as the standard. 10 SWS measurements ...
متن کاملShear-wave elastography for breast masses: local shear wave speed (m/sec) versus Young modulus (kPa)
PURPOSE To evaluate and compare the performance of shear-wave elastography (SWE) for breast masses using the local shear wave speed (m/sec) vs. Young modulus (kPa). METHODS A total of 130 breast lesions in 123 women who underwent SWE before ultrasound- guided core needle biopsy or surgical excision were included. With the region-of-interest placed over the stiffest areas of the lesion on SWE,...
متن کاملPoint shear wave elastography method for assessing liver stiffness.
AIM To estimate the validity of the point shear-wave elastography method by evaluating its reproducibility and accuracy for assessing liver stiffness. METHODS This was a single-center, cross-sectional study. Consecutive patients with chronic viral hepatitis scheduled for liver biopsy (LB) (Group 1) and healthy volunteers (Group 2) were studied. In each subject 10 consecutive point shear-wave ...
متن کاملA comparative study of shear wave speed estimation techniques in optical coherence elastography applications
Optical Coherence Elastography (OCE) is a widely investigated noninvasive technique for estimating the mechanical properties of tissue. In particular, vibrational OCE methods aim to estimate the shear wave velocity generated by an external stimulus in order to calculate the elastic modulus of tissue. In this study, we compare the performance of five acquisition and processing techniques for est...
