Abstract
A method and an apparatus for color mapping of flow power data in which the flow states containing information of most interest to the user are enhanced, while flow states not containing information of interest are suppressed. This is accomplished using a color mapping having three segments which are connected at upper and lower knee points, the latter being settable either automatically or via operator inputs. In the automatic mode, the host computer determines the positions of the knee points based on analysis of a single or a mean image frame of power Doppler data or based on system parameters (e.g., dynamic range) set by the operator. The host computer then constructs a color mapping having the determined knee points and loads that color mapping into the video processor.
