Abstract

Abstract Organ motion is a major problem for Focused Ultrasound Surgery (FUS) of liver tumors. We present a liver phantom mimicking human respiratory motion (20 mm range, 3 − 7 s/cycle) and the evaluation of an ultrasound-tracked steered FUS system on that phantom. Temperature curves are recorded while sonicating in moving and static phantom. The temperature curves correlate well and show the ability of the system to compensate breathing like motion.
