| doppler | The use of an augmented listening device for the purpose of detecting the pulse in an extremity. Use in the evaluation of peripheral (occlusive) vascular disease. (27 Sep 1997) |

| doppler broadening | <radiobiology> Frequency spreading which causes broadening of single-frequency radiation (for example, spectral lines) when the radiating bodies (atoms, molecules, etc.) have different velocities. Radiation from each individual radiating body has a different Doppler shift, and the collection of radiations at different frequencies broadens the peak of the line in an intensity-vs-frequency plot.

| Doppler colour flow | A computer-generated colour image produced by Doppler ultrasonography in which different directions of flow are represented by different hues. This technique is typically used to examine blood flow when evaluating heart disease. Where obstructions (for instance, arterial plaques) exist, blood flow will alter according to the principles of fluid mechanics. Eddies and reversals are readily apparent on the colour image. See: Doppler ultrasonography. (05 Mar 2000) |
| Doppler echocardiography | Use of Doppler ultrasonography techniques to augment two-dimensional echocardiography by allowing velocities to be registered within the echocardiographic image. See: duplex ultrasonography, Doppler ultrasonography. Synonym: duplex echocardiography. (05 Mar 2000) |
| doppler effect | <radiobiology> Variation in the frequency of a wave (as measured by an observer) due to relative motion between the observer and the source of the wave. (The observed frequency increases if the source is moving towards the observer and vice versa.) The equation can be found in most optics texts and many introductory physics texts. (09 Oct 1997) |
| Doppler phenomenon | <radiobiology> Variation in the frequency of a wave (as measured by an observer) due to relative motion between the observer and the source of the wave. (The observed frequency increases if the source is moving towards the observer and vice versa.) The equation can be found in most optics texts and many introductory physics texts. (09 Oct 1997) |
| doppler shift | <radiobiology> The amount of change in the observed frequency of a wave due to the Doppler effect, sometimes called the Doppler frequency. (09 Oct 1997) |
| Doppler ultrasonography | Application of the Doppler effect in ultrasound to detect movement of scatterers (usually red blood cells) by the analysis of the change in frequency of the returning echoes.In many instances, ultrasound has supplanted x-radiography as the imaging method of choice, because it poses no risk to patients, is noninvasive, and of moderate cost. Doppler-corrected ultrasound enables real-time viewing of tissues, blood flow, and organs that cannot be obtained by any other method. It has proved a boon to cardiology, greatly aiding evaluations of cardiovascular patients, and to obstetrics, where it is used for foetal monitoring. (05 Mar 2000) |

| Doppler shift |
The Doppler effect, named after Christian Andreas Doppler, is the apparent change in frequency or wavelength of a wave that is perceived by an observer moving relative to the source of the waves. For waves, such as sound waves, that propagate in a wave medium, the velocity of the observer and the source are reckoned relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from either motion of the source or motion of the observer. ...
