Abstract
An ultrasonic diagnostic imaging system and method are described for performing fundamental frequency and second harmonic frequency imaging simultaneously. Transmit bursts are employed which include a first waveform component optimized for fundamental imaging and a second waveform component optimized for harmonic imaging. The first waveform component may be centered in the transducer passband, and the second waveform component may be located on the opposite side of the center of the transducer passband from its second harmonic frequency, for instance. Echoes received from the bursts are separated into fundamental and harmonic components and used to form separate fundamental and harmonic images or blended fundamental/harmonic images.
