DESCRIPTION (provided by applicant): Low cost high frequency (15, 20 and 25 MHz), and high resolution medical imaging linear array transducers will be designed and constructed for commercial sale under the direction and design of the NIH Resource Center for Ultrasonic Transducer Technology at the University of Southern California. A newly developed high performance ultrasonic scanner, the UltraVision, with the unique feature of having its high speed digital functions entirely within a large Field Programmable Gate Array chip, will be reprogrammed to accommodate the transducers. The UltraVision supports the very advanced features of elastography and optoacoustics and these modes will continue to be functional at these high frequencies. The system will initially be targeted to the morphological and functional imaging of cancer tumors in small animals. The animal studies will be under the direction of the Biomedical Engineering Department of the University of Texas at Austin where Associate Professor Stanislav Emelianov has already guided the UltraVision's design of optoacoustics and elastography. The initial aim is to provide researchers with an accessible tool for cancer research in small animals that will reduce the cost of the science and animal usage. Bringing the new modalities of functional imaging will also increase the specificity of cancer detection and staging. The long term goal is to develop an instrument that will be capable of supporting the emerging field of molecular specific imaging with antibody conjugated nano particles. This new field of optoacoustic imaging of nano particles is very compelling due to their sensitivity, the ability to synthesize their optical spectral absorption, and their non-toxicity. The transducers will be constructed on a 2-2 piezocomposite design known to the investigators Drs. Cannata and Shung and transferred to WinProbe where they will be set up for construction in volumes to be commercialized. The modification to the UltraVision will be largely performed in Very High Speed Integrated Circuit Hardware Description Language, which is not a simple task but it is the only method of accommodating the needs of performing the functions at the required speeds and costs. The acoustic lines will be formed by interlacing and cross-correlation to achieve a very high resolution performance. As the UltraVision Medical Ultrasound System is being commercialized for Breast cancer discrimination and the ageing of thrombi, its price savings from production volume will be shared into the research environment. PUBLIC HEALTH RELEVANCE: This project develops high frequency transducers for a newly developed and uniquely designed medical ultrasonic scanner to image small anatomical structures and to display their functionality. Initially targeted for use in the research of cancer with small animals, its future is seen in the emerging field of functional imaging of the human sentinel lymph nodes with contrast of cancer attaching nano particles. The modifications to the system will be designed to preserve the scanners very low equipment cost.

描述（由申请人提供）：低成本高频（15,20和25mhz）和高分辨率医学成像线性阵列换能器将在南加州大学NIH超声换能器技术资源中心的指导和设计下设计和制造用于商业销售。一种新开发的高性能超声波扫描仪，具有高速数字功能的独特功能，完全在一个大型现场可编程门阵列芯片内，将被重新编程以适应换能器。UltraVision支持弹性成像和光声学的先进功能，这些模式将继续在这些高频率下发挥作用。该系统最初将针对小动物肿瘤的形态和功能成像。动物研究将在德克萨斯大学奥斯汀分校生物医学工程系的指导下进行，那里的副教授Stanislav Emelianov已经指导了紫外线视觉的光声学和弹性成像设计。最初的目标是为研究人员在小动物身上进行癌症研究提供一个方便的工具，从而降低科学研究和动物使用的成本。引入功能成像的新模式也将增加癌症检测和分期的特异性。长期目标是开发一种仪器，能够支持抗体共轭纳米颗粒分子特异性成像的新兴领域。由于纳米粒子的灵敏度、合成光谱吸收的能力和无毒性，这个光声成像的新领域非常引人注目。传感器将构建在2-2压电复合材料的设计已知的研究博士。并转移到WinProbe，在那里他们将进行批量建设，以实现商业化。对超高速集成电路硬件描述语言的修改将主要以超高速集成电路硬件描述语言进行，这不是一项简单的任务，但它是满足以所需速度和成本执行功能需求的唯一方法。声学线将通过交错和相互关联形成，以实现非常高的分辨率性能。随着用于乳腺癌鉴别和血栓老化的医用超声系统的商业化，其批量生产节省的价格将分享到研究环境中。
