U.S.-Western Europe Cooperative Research: Transverse Doppler Experimentation in France and Italy

该奖项将支持德雷克塞尔大学的弗农·纽豪斯博士和两名欧洲研究人员在生物工程方面的合作研究：法国里昂国家健康与医学研究所(INSERM)的多米尼克·卡斯格诺尔博士和意大利佛罗伦萨大学电气工程系的皮耶罗·托托利博士。该项目的目标是找到更准确的血流测量方法。纽豪斯博士和他的研究小组发现了一种新的血流测量方法，即传感器与血流成直角。但需要测试来完善这种方法，并对数据的解释做出更多解释。佛罗伦萨的实验室拥有多普勒系统，其参数可以针对这种横向多普勒方法进行最佳调整。这样的系统在商业上是不可用的。Tortoli博士和他的同事们愿意在模拟的血液流动和活体受试者身上测试这种方法。为了进一步发展横向多普勒法，美国研究人员开发了新的换能器设计，使分离流动参数，如湍流和平均流速成为可能。由凯瑟诺博士领导的里昂研究小组将协助弗农博士构建这些新的换能器形状，并在他的实验室使用仪器进行测试，这种仪器的吸收率很高，在美国并不普遍使用。

This award will support collaborative research in bioengineer- ing between Dr. Vernon Newhouse, Drexel University, and two European investigators: Dr. Dominique Cathignol, National Institute for Health and Medical Research (INSERM), Lyons, France and Dr. Piero Tortoli, Electrical Engineering Department, University of Florence, Italy. The objective of the project is to find more accurate methods of blood-flow measurement. Dr. Newhouse and his research group have discovered a new method of blood-flow measurement, in which the transducer is held at right angles to the blood-flow. But tests are required to perfect this method and to shed more light on the interpretation of data. The laboratory in Florence has Doppler systems whose parameters can be adjusted optimally for this transverse Doppler method. Such systems are not available commercially. Dr. Tortoli and his associates are willing to test this method in simulated blood-flow and living subjects. In order to develop the Transverse Doppler method further, the US investigator has developed new transducer designs which will make it possible to separate flow parameters, such as turbulence and mean flow velocity. The research group in Lyons headed by Dr. Cathignol will assist Dr. Vernon to construct these new transducer shapes and test them with the instrumentation in his laboratory, which is highly sophisti- cated and not generally available in the US.
