Abstract
An ultrasound imaging method for use in the presence of contrast agents is disclosed in which acoustic waves are transmitted at a first fundamental transmission frequency and are focused on at least one scan line. Acoustic beams reflected from the body under examination and the contrast agents are separated into at least one harmonic or subharmonic components along with the fundamental frequency component. The amplitudes of these components compared to determine whether the reflecting material is either body tissue or the contrast agent.
