Abstract:
In an ultrasound machine for generating a display responsive to moving structure within a region of interest of a subject by displaying at least one color characteristic related to a movement parameter of the structure, apparatus for displaying the color characteristic comprising:a front-end arranged to transmit ultrasound waves into the structure and to generate received signals in response to ultrasound waves backscattered from the structure in the region of interest over a time period; a processor responsive to the received signals to generate a set of parameter signals representing values of the movement parameter within the structure during the time period and responsive to the set of parameter signals to generate a color characteristic signal representative of a selected value larger than the mean value of the set of parameter signals; and a display arranged to display a color representation of the moving structure in response to the color characteristic signal.
