Novel Approach to Ultrasonic Transducer Characterization Using the Extended Angular Spectrum Method

这是一种新颖的电子/计算机工程方法来解决从声学信号中推断物理信息的难题。本研究将探讨非线性传播效应，以预测声波在非均匀、非线性组织介质中的传播。一个新的时代正在出现，即内脏器官的无创可视化。这项建议提出了实现这一目标的新方法。这是一个高风险、高利润的提议。这种类型的研究可以在不使用电离辐射的情况下大大有助于内部器官的可视化。

This is a novel electrical/computer engineering approach to the difficult problem of deducing physical information from acoustic signals. This research will address issues concerning nonlinear propagation effects in order to predict propagation of sound waves through inhomogeneous, nonlinear, tissue media. A new era is emerging, namely, non-invasive visualization of internal organs. This proposal suggests a new means for accomplishing this goal. This is a high-risk, high-gain proposal. This type of research could substantially contribute to visualization of internal organs without the use of ionizing radiation.
