Direct Phase-based Strain Estimator for Ultrasound Tissue Elasticity Imaging

Introduction Strain estimation is used when studying and diagnosing tissues that have hardened from disease. Tumors are typical examples of such tissues. Information about stiffness and elasticity obtained from strain estimation help doctors and researchers determine stage and type of disease. Technology description Researchers at the UW have developed a novel method for strain estimation in ultrasound tissue elasticity imaging with the ability to estimate strain from the phase of temporal and spatial correlation between ultrasound signals. This system significantly reduces signal to noise ratio and the contrast to noise ratio of the elastogram. Business opportunity The UW direct phase-based strain estimator for ultrasound tissue elasticity imaging significantly improves accuracy and lesion detectability in ultrasound elasticity imaging. Resolution is also improved allowing improved guidance to biopsy sites. This strain estimator is computationally efficient compared to conventional estimators enabling the real-time implementation and clinical use of this new ultrasound imaging mode. Stage of development Reduced to practice and currently being tested in local hospitals. Intellectual property position U.S. and foreign patents pending Related Publication(s)
