Patent number: 11510652Abstract: A system useful for performing ultrasound elastography of organs such as the liver allows efficient and robust data acquisition. The system may be applied to perform real-time, noninvasive ultrasound imaging of the liver in humans. Steady-state, shear wave absolute elastography is used to measure the Young's modulus of the liver tissue. This method involves the use of an external exciter or vibrator to shake the tissue and generate a shear wave. Accurate placement of an ultrasound transducer facilitates measurement of the tissue motion due to the shear wave. The stiffness of tissues in the region being imaged may be computed from the measured tissue motions. The following innovations address both vibrator and transducer placement, as well as some specific methods to ensure adequate wave propagation, in order to obtain accurate and consistent measurements.Type: GrantFiled: December 19, 2018Date of Patent: November 29, 2022Assignee: The University of British ColumbiaInventors: Septimiu Salcudean, Robert Rohling, Mohammad Honarvar, Julio Raul Lobo, Caitlin Marie Schneider
