ABSTRACT:
Disclosed are a method and apparatus for displaying a tomographic image based upon a non-linear parameterinside an organ. An ultrasonic transducer radiates to the organ ultrasonic burst waves of two different frequencies .omega.1 and .omega.2 at a predetermined time interval, and receives the reflected waves thereof. The reflected waves of .omega.1 and .omega.2 are mixed with each other due to a non-linear effect inside the organ, thereby generating a differential reflected wave of (.omega.1-.omega.2) which is received by the transducer. The intensities of the reflected wave of .omega.1 and the differential reflected wave are stored in a frame memory as a function of time. An operational unit calculates the intensity of the forward wave of .omega.2 at a position of mixing by exponential gain compensation, and then calculates a non-linear parameter from the intensities of the reflected wave of .omega.1, the differential reflected wave and the forward wave of .omega.2 when the mixing occurs. A tomographic image based on the non-linear parameter is displayed by a display unit.
