US Patent Issued to University of Rochester on April 29 for "Reverberant shear wave gradients for ultrasound elastography" (New York, Washington Inventors)

ALEXANDRIA, Va., June 9 -- United States Patent no. 12,285,293, issued on April 29, was assigned to University of Rochester (Rochester, N.Y.).

"Reverberant shear wave gradients for ultrasound elastography" was invented by Juvenal Ormachea (Bellevue, Wash.) and Kevin J. Parker (Rochester, N.Y.).

According to the abstract* released by the U.S. Patent & Trademark Office: "The wave number and phase velocity (shear wave speed) of ultrasound energy within an organ of interest are calculated using a herein-disclosed phase gradient calculation method. This calculation method is less sensitive to imperfections in the reverberant field distribution and requires a smaller support window, relative to earlier calculation methods based on autocorrelati...
