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

这是一种新颖的电气/计算机工程方法， 从声信号中提取物理信息的难题 信号. 这项研究将解决有关非线性问题， 传播效应，以便预测声音的传播 波通过不均匀、非线性的组织介质。 新时代 正在出现，即，内部的非侵入性可视化 机关这项建议提出了一种新的手段， 这个目标 这是一个高风险、高收益的提议。 这种类型 的研究可以大大有助于可视化的 不使用电离辐射的内部器官。

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.
