"In a manner similar to pulsed wave Doppler (PWD), colour flow Doppler utilises intermittent sampling of ultrasound waves thereby avoiding the range ambiguity characteristic of continuous wave Doppler (CWD). Pulsed wave Doppler, however, is limited to the interrogation of flow velocity and direction along a single line at a certain depth (defined by the sample volume or gate); Colour flow Doppler simultaneously interrogates multiple sample volumes (with each pixel representing a sample volume) along an array of scan lines 1."

"There are several general parameters that need to be taken into account to obtain an optimum colour flow Doppler scan: types of transducers, location and number of focal zones, depth of field, 2D gain setting, scan orientation, and image zoom, Specific colour flow Doppler settings such as colour and spectral parameters should also be optimised.5"
