Remote dynamic acoustoelastic testing is proposed to provide a noninvasive and regional measurement of elastic and dissipative acoustic nonlinearities in fluids and solids. The probed medium is dynamically stressed by a low-frequency sinusoidal variation in the hydrostatic pressure in the surrounding fluid. Simultaneously, ultrasound pulses propagate undergoing time of flight and energy modulations, associated with elastic and dissipative nonlinearities, respectively. Acoustic nonlinearities in tension phases can be distinguished from those measured in compression phases. Instantaneous modulations of ultrasound time of flight and energy are analyzed as functions of the instantaneous low-frequency acoustic pressure, similar to a quasistatic acoustoelastic testing.

    Tense ascites is a widely used clinical concept lacking a quantitative correlate. In 13 patients with tense cirrhotic ascites we measured total intraabdominal pressure (IAP), hydrostatic pressure (IIP), and tension. IIP was defined as the level of ascitic fluid determined by percussion of the...
