Complementary-Aperture Pulse Sequencing for Fundamental-Band Nonlinearity Parameter Imaging
Esteban Avilés, Michael Oelze, Roberto Lavarello +1
The depletion method (DM) enables the estimation of the acoustic nonlinearity parameter, B/A, in pulse-echo ultrasound using fundamental-band signals from low- and high-pressure ac…

Closed-form weak-wave propagation pressure amplitudes for arbitrary power-law attenuation
Esteban Avilés, Michael Oelze, Roberto Lavarello +1
Biological tissues exhibit power-law frequency dependence of the attenuation coefficient. We derive closed-form weak-wave expressions for fundamental, second-, and third-harmonic p…
