Semiquantitative and Quantitative Color Flow Mapping Methods

Abstract

Conventional pulsed and continuous-wave Doppler applications have been in use since the mid-1970s. The first color flow mapping system was a color m-mode instrument developed by a Swiss engineer named Brandistini. Stevenson and coworkers utilized this system for cardiac sonographic examinations in the late 1970s, but in general, there was very little interest in the method until the early 1980s, when a 2D color flow mapping system became available. With this new technology and the interest it generated, the development in color flow mapping Doppler technology moved at a rapid pace.
