项目摘要

DESCRIPTION (provided by applicant): The long term objective of this research is to develop new computer software that simulates the propagation of ultrasound through a specified object. Simulation software exists in a variety of engineering disciplines, for example in electromagnetics and stress-strain analysis. Ultrasound simulation is much less common. A two-dimensional ultrasound simulation software package has been available for several years. However, the lack of any 3D ultrasound simulation software has prevented a broader application of such techniques. One area which has suffered has been the use of ultrasound to assess bone, for example, to diagnose and manage osteoporosis. Three-dimensional simulation software would be expected to have a signficant positive impact on furthering understanding on how ultrasound interacts with bone, and ultimately, on developing better devices for bone fracture risk determination. The specific aim of this research is to demonstrate the feasibility of using a standard desktop computer to accurately simulate the full 3D and 3D-axisymmetric solutions to the elastic wave equation, at ultrasonic frequencies. A further specific aim is to simulate the 3D propagation of ultraound through bone. A finite difference approach will be utilized in deriving the algorithms. PROPOSED COMMERCIAL APPLICATIONS: Computer software for 3D simulation of ultrasound would have widespread use. A 2D version of the software has been sold to many commercial and academic institutions around the world. Considering the more realistic representations offered by the 3D software to be developed in this proposal, it is expected that even a broader market would be reached. Applications broader than bone and osteoporosis, such as in non-destructive testing in general, would be expected to significantly increase.

描述（由申请人提供）：这项研究的长期目标是开发新的计算机软件来模拟超声波通过特定物体的传播。仿真软件存在于各种工程学科中，例如电磁学和应力应变分析。超声模拟不太常见。二维超声模拟软件包已经面世多年。然而，缺乏任何 3D 超声模拟软件阻碍了此类技术的更广泛应用。受到影响的一个领域是使用超声波来评估骨骼，例如诊断和治疗骨质疏松症。三维模拟软件预计将对进一步了解超声波与骨骼的相互作用产生显着的积极影响，并最终开发更好的骨折风险确定设备。这项研究的具体目的是证明使用标准台式计算机在超声波频率下精确模拟弹性波方程的完整 3D 和 3D 轴对称解的可行性。另一个具体目标是模拟超声波通过骨骼的 3D 传播。将利用有限差分方法来推导算法。拟议的商业应用：用于超声波 3D 模拟的计算机软件将得到广泛的应用。该软件的 2D 版本已出售给世界各地的许多商业和学术机构。考虑到本提案中将开发的 3D 软件提供的更真实的表示，预计将达到更广阔的市场。比骨骼和骨质疏松症更广泛的应用，例如一般的无损检测，预计将显着增加。
