测量人体内的血流速度对诊断疾病和研究生理有重要价值。用超声多普勒效应可以无创伤地测量血流速度。但由于血管在皮层下面,测量时,声束与血管间夹角不能确定,影响了测量结果。因此一般的超声多普勒仪器都不能定量地测定血流速度。我系超声多普勒研究组根据相互独立的双超声束多普勒效应,定量测定血流速度,并研制成T-2型超声多普勒血流速度计。该仪器于1982年荣获上海市重大科研成果二等奖,并于1984年12月获
Measuring blood flow in a human body is valuable for diagnosing disease and studying physiology. Doppler ultrasound can be used to measure blood flow velocity noninvasively. However, the blood vessels in the cortex below the measurement, the angle between the sound beam and the blood vessels can not be determined, affecting the measurement results. Therefore, the general ultrasonic Doppler apparatus can not quantitatively determine the blood flow velocity. I Department of Ultrasound Doppler study group based on independent of each other double-beam Boppler effect, quantitative determination of blood flow velocity, and developed into T-2-Doppler flowmeter. The instrument in 1982 won the second prize of major scientific research in Shanghai, and in December 1984 won
