Abstract
A medical diagnostic ultrasound imaging system and method modulate the image signal as a function of the ratio of the harmonic receive signal to the fundamental receive signal. Tissue harmonic backscatter differs substantially in spectral shape as compared to contrast agent backscatter, and this method allows improved discrimination between contrast agent and tissue backscatter.
