摘要：
Systems and methods for maintaining the alignment of a therapeutic ultrasound applicator to a target site are described. Overlapping ultrasound signals are sent to a target tissue site and the echo detected. An algorithm is described for detecting tissue movement relative to the applicator based on comparison of the echo with a previously stored echo.
