Claim Text:
1. 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 having a first end and a second end, 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; a calibration weight holder attached to the second end; and 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; wherein the radiation force balance calibrator is constructed of non-magnetic materials, and further comprises a processor and a memory, the memory comprising instructions for execution by the processor, wherein execution of the instructions causes the processor to perform:
