Abstract
A method and system for detecting energy using pulse inversion and Doppler processing are provided. Pulse inversion may be used to image the harmonic response of tissue alone or with contrast agents. Lowpass or bandpass clutter filters suppress the harmonic and/or fundamental response of tissue clutter to provide improvements in imaging, such as for imaging small vessels. Elimination of tissue clutter from both the fundamental components and second harmonic components in the Doppler domain increases the specificity of contrast agent and/or tissue.
