Ultrasonic harmonic imaging system and method

摘要

The system described ultrasonically images a target with energy spreading transmissions. Generally, ultrasonic energy corresponding to a line focus is transmitted into a target at a fundamental center frequency. The target may or may not include contrast agents. In either case, echoes are received at a harmonic of the fundamental center frequency. Echoes are also received at the fundamental center frequency. The echoes received at the harmonic center frequency are efficiently compounding with the echoes received at the fundamental center frequency.
