Velocity7
  • Doppler ultrasonography is medical ultrasonography that employs the Doppler effect to perform imaging of the movement of tissues and body fluids (usually blood), and their relative velocity to the probe. (wikipedia.org)
  • In spectral Doppler, the y-axis shows the direction and velocity of the flow. (wikipedia.org)
  • All modern ultrasound scanners use pulsed Doppler to measure velocity. (wikipedia.org)
  • The major advantage of pulsed wave Doppler (PW Doppler) over continuous wave (CW Doppler) is that distance information is obtained (time between transmitted and received pulses multiplied by sound velocity equals distance) and gain correction is applied. (wikipedia.org)
  • The terms Doppler ultrasound and Doppler sonography have been accepted to apply to both pulsed and continuous Doppler systems, despite the different mechanisms by which the velocity is measured. (wikipedia.org)
  • Doppler Study of Portal Vein and Renal Venous Velocity Predict the Appropriate Fluid Response to Diuretic in ICU: A Prospective Observational Echocardiographic Evaluation. (emedicalacademy.com)
  • The assessment of aortic valve stenosis (AS) severity based on Doppler velocity and pressure gradient is flow dependent. (emedicalacademy.com)
