[Renal transplant blood flow measurement using ultrasonic contrast agents].
We studied the renal transplant blood flow using an ultrasonic contrast agent. The contrast medium was injected intravenously and produced blood flow enhancement for at least 60 seconds. Measurements were made from the recorded Doppler spectra. Fourteen renal transplant recipients were investigated by color Doppler echography. Blood flow in the interlobular artery could be analyzed in all patie...
متن کاملUltrasonic measurement of gas flow using electrostatic transducers.
Ultrasonic gas flowmeters typically use narrowband piezoelectric transducer arrangements for interrogating the flow of gas in a pipe. In this work, the suitability of broadband electrostatic transducers operating at frequencies of up to 1 MHz for ultrasonic measurement of gas flow has been investigated. The transit time method of ultrasonic gas flow measurement was adopted and experiments were ...
متن کاملMeasurement System of Two-phase Flow Using Ultrasonic Velocity Profile Monitor
The experimental apparatus was composed of a water circulation system, an air supply system, a test section and a measurement system~ Air and water were used as working fluids. . The test section was a vertical rectangular channel of 10mmxlOOmmx700mm made of Plexiglas as shown in Fig.l. The measuremen.t system consisted of the UVP and a personal computer to record and treat data. Water was fed ...
متن کاملTwo-Dimensional Automatic Measurement for Nozzle Flow Distribution Using Improved Ultrasonic Sensor
Spray deposition and distribution are affected by many factors, one of which is nozzle flow distribution. A two-dimensional automatic measurement system, which consisted of a conveying unit, a system control unit, an ultrasonic sensor, and a deposition collecting dish, was designed and developed. The system could precisely move an ultrasonic sensor above a pesticide deposition collecting dish t...
متن کاملMeasurement Algorithm of Two-Dimensional Wind Vector using Ultrasonic Transducers
Ultrasonic wind speed measurement technique obtains more and more extensive use in the field of Meteorology and Environmental Protection etc. When designing an ultrasound wind vector instrument, synthesizing wind vector information, containing wind velocity vector and wind angle, is of prime importance to accomplish accurate measurement. This paper presents synthesis algorithm of ultrasonic 2D ...
