Principles and physics of Doppler.
This article reviews the available Doppler instrumentation and application to assessment of blood flow velocity. A review of the basis of quantitative measurements such as volume flow, modified Bernoulli and continuity equations, and pressure half-time are discussed. A brief technical description of Doppler color-flow mapping is presented with reference to data acquisition and display.
