A Mechanical System Identification Method for Non-Invasive Ultrasound Theragnostic System

Abstract: In this paper, we propose a mechanical system identification method for the Non-Invasive Ultrasound Theragnostic System (NIUTS). NIUTS tracks and follows the movement in an affected area (kidney stones, in the present study) by irradiating the area with high-intensity focused ultrasound (HIFU). Blur noise caused by oscillation of the mechanical systems deteriorates the servoing performance. To enhance the servoing performance, it should be required to identify the mechanical system with mechanical oscillation part.
