Abstract
The shape and size of the energy transducer' s focus decide the constitution of the cure project using HIFU ( High intensity focused ultrasound). The parameter of the focus will be different when the structure of the transducer is different, so we must calibrate each of them. This paper represents calibration principle and method of focal territory in a high-power ultrasonic focus transducer. The experiment is performed on our designed multiple wafer concave focus probe and HIFU apparatus, using 1010 nylon and pork as the target range.It can be seen that the geometric center and focal territory acoustic field center cannot match together. When using nylon as the target, the distributed curves and theoretical curves are a better match. Therefore, the method and principle of calibration here is constructive for the calibration on pictures of other types of HIFU apparatus.关键词
