doppler measurement
1Doppler echocardiography — Intervention Mitral valve MeSH …
2Doppler effect — Change of wavelength caused by motion of the source. An animation illustrating how the Doppler effect causes a car engine or siren to soun …
3Doppler spectroscopy — Diagram showing how a smaller object (such as an extrasolar planet) orbiting a larger object (such as a star) could produce changes in position and velocity of the latter as they orbit their common center of mass (red cross). Doppler spectroscopy …
4Doppler error — In using Doppler radar, the error in the measurement of target radial velocities as a result of atmospheric refraction. These errors result, first, from the assumption of a constant wave velocity for a nonhomogeneous atmosphere and, second, the… …
5Laser-Doppler-Anemometrie — 2D Laser Doppler Anemometer an einem Strömungskanal. Zwei Strahlpaare leicht unterschiedlicher Wellenlänge dienen der Messung der Längs bzw. vertikalen Komponente der Strömungsgeschwindigkeit am Ort des Schnittpunkts. Das Objektiv ist mit dem… …
6Laser-Doppler-Anemometer — Die Laser Doppler Anemometrie (LDA) ist ein berührungsloses optisches Messverfahren zur Bestimmung von Geschwindigkeitskomponenten in Fluidströmungen (Flüssigkeiten und Gase). Hierbei wird ein Laserstrahl mit Hilfe eines Strahlteilers in zwei… …
7laser-Doppler velocimetry — measurement of the flow of red cells in a microcirculatory bed by means of laser light delivered to and detected from the region of interest by fiberoptic probes …
8Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… …
9Non-invasive intracranial pressure measurement methods — Increased intracranial pressure (ICP) is one of the major causes of secondary brain ischemia that accompanies a variety of pathological conditions, most notably, traumatic brain injury (TBI), stroke, and intracranial hemorrhages. However, aside… …
10Transcranial doppler — (TCD) is a test that measures the velocity of blood flow through the brain s blood vessels. Used to help in the diagnosis of emboli, stenosis, vasospasm from a subarachnoid hemorrhage (bleeding from a ruptured aneurysm), and other problems, this… …
