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.
2010-026 – Accelerated MRI: A method is described for improving parallel acquisition along the longitudinal direction.
2009-281 – An ultrasound imaging system transmits a train of pulses along each scan line. The pulses are reflected at various depths and interfaces (objects). In color Doppler mode, the reflected signals from the corresponding scan line and depth correlated frame by frame. A loss of correlation is interpreted as object displacement and indicated by a color overlay. Even if an object does not move... Read More
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)
