Cervical elastography strain ratio and strain pattern for the prediction of a successful induction of labour

Journal of Perinatal Medicine, 2020
Abstract Objectives The aim of this study was to introduce cervical strain elastography to objectively assess the cervical tissue transformation process during induction of labour (IOL) and to evaluate the potential of cervical elastography as a predictor of successful IOL.

Auto strain ratio system for the quality control of breast strain elastography

Journal of Medical Ultrasonics, 2017
To determine the reproducibility, accuracy, and quantitative values of the auto strain ratio system (ASRS)-a newly developed strain elastography-based program.First, the accuracy of ASRS was verified using a breast phantom. A prospective clinical study was then performed in patients.

Theoretical bounds on strain estimation in elastography

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1995
Elastography is a technique for the estimation of tissue elasticity that is based on the estimation of strain. Tissue strain can be estimated by finite difference computations of echo time-delay. Echo time-delays are obtained by cross-correlation processing of pre- and post-compression echo signals. Errors in strain estimation can be expressed in terms

Wavelet transform-based strain estimator for elastography

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1999
A new signal processing algorithm based on a wavelet transform (WT) is proposed for instantaneous strain estimation in acoustic elastography. The proposed estimator locally weighs ultrasonic echo signals acquired before tissue compression by a Gaussian window function and uses the resulting waveform as a mother wavelet to calculate the WT of the ...
