Conception, development, innovation, introduction, and validation are some of the steps in the introduction of new technologies and their clinical applications. More than 50 years ago, Doppler techniques and applications were introduced into echocardiography. An important further addition was the introduction of color as a medium for the display of Doppler information. The amplitude of the returning ultrasound signal has been used to generate a black and white image of structure. The phase shift between the transmitted and returning Doppler signal has been used to display Doppler shift information in color. This review focuses on some of the resources critical to this new development, the challenges imposed by the introduction of a new color display, and some of the early clinical validation and applications of color Doppler echocardiography.

概念，开发，创新，引入和验证是引入新技术及其临床应用的一些步骤。50多年前，多普勒技术和应用被引入超声心动图。另一个重要的补充是引入了彩色作为显示多普勒信息的媒介。返回的超声信号的幅度已用于生成结构的黑白图像。已发送和返回的多普勒信号之间的相移已用于以彩色显示多普勒频移信息。这篇综述着重于对这一新发展至关重要的一些资源，采用新的彩色显示器所带来的挑战以及彩色多普勒超声心动图的早期临床验证和应用。
