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，以模拟通过指定对象的超声传播。模拟软件存在于各种工程学科中，例如电磁和应力 - 应变分析。超声模拟不那么普遍。二维超声仿真软件包已有几年了。但是，缺乏任何3D超声仿真软件都无法更广泛地应用此类技术。遭受的一个区域是使用超声来评估骨骼，例如诊断和管理骨质疏松症。预计三维仿真软件将对超声如何与骨骼相互作用，并最终开发出更好的骨骼断裂风险确定设备，从而产生显着的积极影响。这项研究的具体目的是证明使用标准台式计算机以超声频率以弹性波方程式准确模拟整个3D和3D轴对称解。另一个具体的目的是模拟通过骨骼的3D传播。得出算法，将使用有限的差异方法。建议的商业应用程序：用于超声模拟的3D模拟计算机软件将广泛使用。该软件的2D版本已出售给全球许多商业和学术机构。考虑到本提案中要开发的3D软件提供的更现实的表示形式，预计甚至将达到更广泛的市场。预计将比骨骼和骨质疏松症更广泛，例如在非破坏性测试中，预计将显着增加。
