Ultrasonic imaging system and method for displaying composite fundamental and harmonic images

摘要

An ultrasonic imaging system and method acquire fundamental mode and harmonic mode ultrasonic image signals from a subject with a transducer. These image signals are then combined to form a composite image. This composite image includes a nearfield image region modulated primarily as a function of the fundamental mode ultrasonic image signals, and a middlefield or farfield image region modulated primarily as a function of the harmonic mode image signals. In this way, excellent images can be obtained throughout the imaged range.
