1. An ultrasonic diagnostic imaging system which produces images from linear and nonlinear ultrasonic signal components comprising:

  • a transmitter which transmits a series of one or more differently modulated transmit pulses;

    a receiver which receives echo signals in response to the transmit pulses;

    a signal processor, responsive to the received echo signals, which calculates both linear and nonlinear echo signal components;

    a segmentation processor, responsive to both the linear and nonlinear echo signal components, which acts to determine the predominant characteristic of an echo signal on the basis of the relative power of the linear and nonlinear signal components; and

    a display processor, responsive to the segmentation processor, which displays an echo signal on the basis of the determined predominant characteristic.
