Difference Autocorrelation: A Novel Approach to Estimate Shear Wave Speed in the Presence of Compression Waves
Hamidreza Asemani, Jannick P. Rolland, Kevin J. Parker
In share wave elastography (SWE), the aim is to measure the velocity of shear waves, however unwanted compression waves and bulk tissue motion pose challenges in evaluating tissue…
Multiparametric quantification and visualization of liver fat using ultrasound
Jihye Baek, Ahmed El Kaffas, Aya Kamaya +2
Objectives- Several ultrasound measures have shown promise for assessment of steatosis compared to traditional B-scan, however clinicians may be required to integrate information a…
Angular Integral Autocorrelation for Speed Estimation in Shear Wave Elastography
Hamidreza Asemani, Irteza Enan Kabir, Juvenal Ormachea +3
The utilization of a reverberant shear wave field in shear wave elastography has emerged as a promising technique for achieving robust shear wave speed (SWS) estimation. However, a…
WATUNet: A Deep Neural Network for Segmentation of Volumetric Sweep Imaging Ultrasound
Donya Khaledyan, Thomas J. Marini, Avice OConnell +6
Objective. Limited access to breast cancer diagnosis globally leads to delayed treatment. Ultrasound, an effective yet underutilized method, requires specialized training for sonog…
Limitations of curl and directional filters in elastography
Kevin J. Parker
In the approaches to elastography, two mathematical operations have been frequently applied to improve the final estimate of shear wave speed and shear modulus of tissues. The vect…
Improving the diagnosis of breast cancer based on biophysical ultrasound features utilizing machine learning
Jihye Baek, Avice M. O'Connell, Kevin J. Parker
The improved diagnostic accuracy of ultrasound breast examinations remains an important goal. In this study, we propose a biophysical feature based machine learning method for brea…
