2012-129 – A method to quantify tissue viscoelastic properties in a model-independent way by estimating the complex shear modulus from creep-recovery response and shear wave propagation speed by ultrasound acoustic radiation force. This method uses a formula that converts creep-recovery response in time to frequency domain complex modulus. The shear wave speed is used to calibrate the complex modulus... Read More
2011-274 – The invention uses ultrasound to measure the nonlinear mechanical properties of an object including those of biological tissues. This information can be used to detect abnormalities in tissues.
2007-067 – This disclosure is based on the continuing development of our technique Shearwave Dispersion Ultrasound Vibrometry or SDUV (2004-237 & 2006-088) which non-invasively quantifies tissue stiffness and viscosity with ultrasound. Herein we propose methods to generate and detect larger SDUV motions for in vivo applications. (vibrometry) (SDUV)
2003-185 – The invention describes a new algorithm and hardware architecture to compute the fast Fourier transform (FFT). The new algorithm uses a divide and conquer approach to reduce an N point FFT to a plurality of sqrt(N) point FFTs arranged in a pipeline configuration. A new specialized center element joins identical, conventional pipeline FFT units together and provides the necessary control logic... Read More
