  • Systems and methods of high frame rate streaming for treatment monitoring
    Patent number: 9247921
    Abstract: Systems and techniques of treatment monitoring include acquiring channel data from each of a plurality of channels of a signal array over a plurality of frames, determining a reconstruction matrix based on a reconstruction operation to be performed on the channel data, applying the reconstruction matrix to the channel data to obtain reconstructed channel data, estimating displacement data representing displacement of an object over the frames from the reconstructed channel data; determining a conversion matrix based on a conversion operation to be performed on the reconstructed channel data, and applying the conversion matrix to the reconstructed channel data to obtain a displacement map.

  • SYSTEMS AND METHODS FOR ESTIMATING ACOUSTIC ATTENTUATION IN A TISSUE
    Publication number: 20150297188
    Abstract: Systems and techniques for estimating acoustic attenuation in a tissue from time-varying radiation force information generated through the application of acoustic energy to the tissue from at least first and second focal depths are provided. An exemplary technique includes acquiring first signals representing oscillatory motion of the tissue in response to the radiation force proximate the first focal depth, and acquiring second signals representing oscillatory motion of the tissue in response to the radiation force proximate the second focal depth. The technique further includes estimating the oscillatory motion of the tissue from each of the first and second signals, and estimating the acoustic attenuation in the tissue from the estimated oscillatory motion of the tissue from the first and second signals.
