ABSTRACT:
A monochrome image of a cross-section of a body and a color representation of the velocity of blood flow therein are combined so that they are mutually exclusive by causing each pixel of a display to be in monochrome when a signal from which a velocity indicative signal may be derived is less than a minimum value or when that signal exceeds the minimum value and a weighted value of the velocity indicative signal is less than a weighted value of the signal for the monochrome image, and to be in color when the signal from which a velocity indicative signal may be derived exceeds the minimum value and a weighted value of a signal indicative of velocity exceeds a weighted value of the signal for the monochrome image.
