Abstract
A method for detecting the presence of contrast agent in the body of the patient initially transmits ultrasound pulses along respective acoustic scan lines, which pulses exhibit a fundamental transmission frequency. A set of returned signals are received along a respective scan line after each pulse transmission. The return signals are mathematically reconstructed to provide a first spectral component around the fundamental frequency and a second spectral component around a harmonic frequency. The peak amplitude of the reconstructed spectral components are compared to determine whether a contrast agent is present in the tissue, and hence to differentiate myocardium and perfused myocardium.
