Nonlinear Ultrasonic Phased Array Imaging [PDF]

open access: bronzePhysical Review Letters, 2014
This Letter reports a technique for the imaging of acoustic nonlinearity. By contrasting the energy of the diffuse field produced through the focusing of an ultrasonic array by delayed parallel element transmission with that produced by postprocessing of sequential transmission data, acoustic nonlinearity local to the focal point is measured. Spatially
