这封信报告了一种声学非线性成像技术。通过对比由延迟的平行元件传输的超声阵列的聚焦所产生的扩散场的能量与由顺序传输数据的后处理所产生的扩散场的能量，测量了焦点局部的声学非线性。空间隔离波失真推断，而不需要在检查点的波的询问，从而允许通过深度的非线性成像。
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 isolated wave distortion is inferred without requiring interrogation of the wave at the inspection point, thereby allowing nonlinear imaging through depth.
