Abstract
A radiation force balance calibrator () for calibrating a high intensity focused ultrasound transducer (), the radiation force balance calibrator comprising: a balance frame (); a force sensor () for measuring force, wherein the force sensor is attached to the balance frame; a balance () with first () and second ends (), wherein the first end is attached to a pivot () for enabling the balance to pivot relative to the balance frame, wherein the second end is adapted for exerting force onto the force sensor; an oil target phantom () connected to the balance for absorbing ultrasound radiation () from the high intensity focused ultrasound transducer, wherein the absorption of ultrasonic radiation causes a reduction in the force exerted by the balance on the force sensor; and wherein the radiation force balance calibrator is constructed of non-magnetic materials.
