Abstract
Method and system for ultrasound imaging of body tissue in which a focused ultrasound (FUS) transducer (20) is oriented relative to the body such that ultrasonic waves generated by the FUS transducer (20) are directed toward the tissue being imaged. The FUS transducer (20) is operated to cause the formation of microbubbles (28) in the tissue and an ultrasound image of the tissue with the microbubbles (28) is acquired. Phase aberration in the acquired ultrasound image may be corrected, if necessary, using each microbubble (28) as a point source or point-like scatterer. Microbubble (28) formation can therefore be obtained in a non-invasive manner since FUS-induced microbubble (28) formation does not require the insertion of interventional tools into the body.
