Abstract
Improved ultrasound images of a patient's tissue region of interest (ROI) are achieved through the use of a contrast agent. The method includes the steps of: administering the contrast agent to the patient's circulatory system; providing a user interface which enables a user to select a target region within the tissue ROI to be irradiated and to operate an ultrasound transducer to irradiate the selected target region with sufficient ultrasound energy to substantially reduce a backscatter effect of contrast agent that is present therein; and operating an ultrasound transducer to image the tissue ROI. It is preferred that the contrast agent be encapsulated into microbubbles The method is further applicable to selective destruction of encapsulated therapeutics which arrive at a tissue ROI to which the therapeutic is to be administered.
