Velocity measurements of blood flow are also used in other fields of [[medical ultrasonography]], such as [[obstetric ultrasonography]] and [[neurology]]. Velocity measurement of blood flow in arteries and veins based on doppler effect is an effective tool for diagnosis of vascular problems like stenosis. -->

Instrumentoj -ekz. Lazera Doppler-Rapidometro(LRD) kaj Akustika Doppler-Rapidometro (ADR)- disvolviĝas por mezuri rapidojn en fluaĵoj. Pri LDR kaj ADR, radio de lumo aŭ de sono estas elsendita, la Dopplera ŝoviĝo estas mezurita post
<!-- Instruments such as the [[laser Doppler velocimetry|laser Doppler velocimeter]] (LDV), and [[Acoustics|Acoustic]] Doppler Velocimeter (ADV) have been developed to measure [[velocity|velocities]] in a fluid flow. The LDV and ADV emit a light or acoustic beam, and measure the doppler shift in wavelengths of reflections from particles moving with the flow. This technique allows non-intrusive flow measurements, at high precision and high frequency.
