  • Noninvasive Vascular Diagnosis
    In the conventional continuous wave Doppler instrument , separate transmitting and receiv- ing transducers are used that operate constantly to detect flow at any point along the sound beam.
  • Noninvasive Vascular Diagnosis
    Table 2.1 Suggested curriculum for physicians interpreting in the vascular laboratory Pathophysiology of vascular disease including arterial (atherosclerotic and nonatherosclerotic), venous, and lymphatic Ultrasound physics, Doppler instruments , transducer technology Basis of physiologic testing (ABI, PPG, APG) Duplex imaging of arteries, veins …
  • Doppler sonography in obstetrics and gynecology
    These different speeds can through the decoded so-called spectral analysis of the Doppler apparatus and through different signal compositions and to be indicated to signal intensities (⊡ Abb. 2.2).

  • Review of methodological developments in laser Doppler flowmetry
    A laser Doppler instrument output often gives flux, velocity and concentration of the moving blood cells.
  • Doppler Ultrasound in Obstetrics and Gynecology
    With most Doppler instruments the high-pass filter is adjustable.
  • Comparison between laser diffraction and phase Doppler velocimeter techniques in high turbidity, small diameter sprays
    The length of the probe volume of the phase Doppler instru- ment was limited by the 200 gm effective width of the slit type spatial filter, so the phase Doppler data will be referred as point measurements.
  • Encyclopedia of Remote Sensing
    In fact, the European Space Agency’s Atmospheric Laser Doppler Instrument (ALADIN), a Doppler lidar in the Atmospheric Dynamics Mission (ADM) with atmospheric wind field measure- ments as its primary objective, is fundamentally an HSRL and will be used for investigations of aerosol …
