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

该奖项将支持德雷塞尔大学的Vernon Newhouse博士和两名欧洲研究人员之间的生物工程合作研究：法国里昂国家卫生与医学研究所（INSERM）的Dominique Cathignol博士和意大利佛罗伦萨大学电气工程系的Piero Tortoli博士。该项目的目标是找到更准确的血流量测量方法。纽豪斯博士和他的研究小组已经发现了一种新的血流量测量方法，在这种方法中，传感器与血流量成直角。但需要进行测试来完善这种方法，并进一步阐明对数据的解释。佛罗伦萨的实验室有多普勒系统，其参数可以为这种横向多普勒方法进行最佳调整。这种系统在商业上是不可用的。托托利博士和他的同事们愿意在模拟血流和活体上测试这种方法。为了进一步发展横向多普勒方法，美国研究人员开发了新的传感器设计，这将使分离流动参数成为可能，如湍流和平均流速。由Cathignol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，并在他的实验室用仪器进行测试，这是非常复杂的，在美国通常是不可用的。

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.
