Abstract
An ultrasound machine is disclosed that displays a color representation of moving structure, such as a cardiac wall tissue, within a region of interest on a monitor. The color representation is generated by displaying color hues corresponding to a movement parameter of the structure, such as velocity or strain rate in such a manner as to provide for quantitative visualization of movement parameter gradients. The movement parameter is mapped to the color hues by apparatus comprising a user interface that allows the user to input color band resolution and a local range of relative parameter values. A front-end generates received signals in response to ultrasound waves. A Doppler processor generates a set of parameter signals representing absolute values of the movement parameter within the structure. A set of color characteristic signals is generated by a display processor in response to the set of parameter signals and to a user-defined local range of relative parameter values. The color characteristic signals, representative of the gradient of the movement parameter of the moving structure, are displayed as a color representation on a monitor.
