The purpose of this review is to help in understanding the principles of a new ultrasound Doppler technique called amplitude-coded colour Doppler (power) mode. All pertinent information available in the literature on the physical principles of this technique has been revised in order to give a detailed survey. The main components and the key characteristics of this mode are discussed together with illustrative examples. In addition, work-in-progress developments and other future aspects of US imaging in combination with this technique are discussed.
