Ultrasound tracked motion compensated focused ultrasound system evaluated on ex vivoovine livers
KeywordsTarget Position Focal Spot Temperature Curve Anatomical Position Focus Ultrasound
The application of FUS in abdominal organs such as the liver or the kidneys is impeded by a number of complications. One of the most challenging is organ motion due to breathing. To achieve ablation in a target within a moving organ the FUS system has to be steered to focus on the same anatomical position. We present a prototypical system that tracks the motion of an ex vivo ovine liver via diagnostic ultrasound (US) and adjusts the focal spot to a fixed anatomical position.
