The Difference Between Colour Doppler Velocity Imaging and Power Doppler Imaging [PDF]
European Heart Journal - Cardiovascular Imaging, 2002 The Doppler effect, which occurs on the reflection of ultrasound from moving blood or tissue, is observed as a shift in frequency of the reflected ultrasound from that of the incident ultrasound. This Doppler shift has been widely used in clinical practice as a means of measuring blood velocity.

Ultrasonic colour Doppler imaging [PDF]
Interface Focus, 2011 Ultrasonic colour Doppler is an imaging technique that combines anatomical information derived using ultrasonic pulse-echo techniques with velocity information derived using ultrasonic Doppler techniques to generate colour-coded maps of tissue velocity superimposed on grey-scale images of tissue anatomy. The most common use of the technique is to image

Orbital colour doppler imaging [PDF]
Eye, 1993 Colour Doppler imaging (CDI) is an ultrasonic method for qualitatively and quantitatively assessing blood flow. Recently this technique has been adapted for investigation of the orbital, optic nerve and ocular vasculature. We discuss the history, principles and methodology of this examination technique for ophthalmology.

Doppler Imaging of Exoplanets and Brown Dwarfs [PDF]
, 2014 Doppler Imaging produces 2D global maps of rotating objects using high-dispersion spectroscopy. When applied to brown dwarfs and extrasolar planets, this technique can constrain global atmospheric dynamics and/or magnetic effects on these objects in un ...

Mobility and transverse flow visualization using phase variance contrast with spectral domain optical coherence tomography [PDF]
, 2007 Phase variance-based motion contrast is demonstrated using two phase analysis methods in a spectral domain optical coherence tomography system. Mobility contrast is demonstrated for an intensity matched Intralipid solution placed without flow within ...

Doppler Imaging and Histology of the Synovium [PDF]
The Journal of Rheumatology, 2012 To the Editor: It is possible to examine the inflammation of a joint, bursa, or tendon area with ultrasonography (US) using greyscale or Doppler imaging1. The detection of perfusion in synovium is a relatively new phenomenon in rheumatology and the detection of a Doppler signal in the synovium is also thought to reflect the inflammatory state2 ...

International Astronomical Union Colloquium, 1993 AbstractThe mapping of stellar surfaces using the observed profiles of spectral lines is described. The problem is expressed in terms of an integral equation to be solved, using Tikhonov’s method. The local line profiles may be given either by an analytic approximation or by the solution of the equation of transfer with a model atmosphere.

Differential rotation on the young solar analogue V889 Herculis [PDF]
, 2010 V889 Herculis is one of the brightest single early-G type stars, a young Sun, that is rotating fast enough (P_rot =1.337 days) for mapping its surface by Doppler Imaging.

ACC Current Journal Review, 1996 Summary Doppler tissue imaging is a novel means of imaging that interrogates high amplitude, low velocity echoes in the range of tissue and myocardial motion. In addition to providing a qualitative aid in edge detection and wall motion analysis, quantitative interrogation of myocardial velocities may provide insights into normal and abnormal systolic
