Focused ultrasound thermal surgery, imaging, and elastometry using the same phased array: feasibility study

A multifunctional array capable of imaging, surgery, and real-time surgery monitoring would significantly improve current focused ultrasound procedures. We tested a 24-element array to determine the feasibility of building a full, 128-element array capable of all three functions. The test array results suggested that a 128-element array would have sufficient power output and imaging capabilities to perform B-mode imaging, focused ultrasound surgery, and localized harmonic motion imaging for monitoring surgery.
