We propose using a patented multi-pulse contrast imaging technique to improve breast ultrasound imaging. This technique applies two acoustic fields one for bubble excitation and the other for imaging. The excitation field will momentarily increase bubble sizes resulting in an increase in the number of bubbles with a size close to the resonance size corresponding to the second imaging field. If the imaging field is applied simultaneously with or slightly after the excitation field, acoustic scattering from bubbles around resonance size becomes markedly stronger than without the excitation field.
