Abstract

An active contrast imaging enhancement technique has been developed for use with microbubble contrast agents. It employs two acoustic fields: an excitation field for conditioning microbubbles and an imaging field for detecting microbubbles. Up to 14.5 and 16 dB increases (due to microbubble conditioning) in scattered first and second harmonic signals respectively were obtained. This technique is unique for effectively enhancing the blood-to-tissue image contrast
