Doppler analysis of flow velocity profile at the aortic root.
This study of aortic root flow velocity profiles suggests that the flow velocity pattern is parabolic rather than flat as has been widely supposed. To analyze the distribution of flow velocity, a special ultrasound pulsed Doppler velocity flow meter, with a direct probe on the aortic wall, was designed. Sixteen patients, none with a diagnosis of aortic valve disease, were examined just before u...
متن کاملFlow measurement at the aortic root - impact of location of through-plane phase contrast velocity mapping
BACKGROUND Cardiovascular magnetic resonance (CMR) is considered the gold standard of cardiac volumetric measurements. Flow in the aortic root is often measured at the sinotubular junction, even though placing the slice just above valve level may be more precise. It is unknown how much flow measurements vary at different levels in the aortic root and which level corresponds best to left ventric...
متن کاملDoppler aortic flow velocity measurement in healthy children.
To determine normal values for Doppler parameters of left ventricular function, ascending aortic blood flow velocity was measured by pulsed wave Doppler echocardiography in 63 healthy children with body surface area (BSA) < 1 m(2) (age < 10 yr). Peak velocity was independent of sex, but increased with body size. Mean acceleration was related to peak velocity (r = 0.75, p < 0.0001). Both stroke ...
متن کاملMeasurement of fluid-flow-velocity profile in turbid media by the use of optical Doppler tomography.
Optical Doppler tomography is demonstrated to be a simple, accurate, and noncontact method for measuring the fluid velocity of laminar flow in small-diameter (~0.5-mm) ducts. Studies are described that utilize circular (square) plastic (glass) ducts infused with a moving suspension of polymer microspheres in air and buried in an optically turbid medium. The measurement of Doppler-shifted freque...
متن کاملLaser Doppler Velocity Profile Sensor: Technical Advances for the Optical Flow Rate Measurement of Natural Gas
− The precise measurement of the flow rate of natural gas is of vital economical importance since natural gas contributes highly to the total energy mix. In this paper we report about a laser Doppler velocity profile sensor specifically designed to suit the measurement conditions at the optical test facility of the German natural gas flow rate standard. The profile sensor is an extension of the...
