Experiments on the 3 D Tracking and Destroying Stone by the Non-Invasive Ultrasound Theragnostic System

Abstract

The authors have developed an non-invasive ultrasound theragnostic system. The concept of the proposed system is to destroy stones and tumors by applying high intensity focused ultrasound (HIFU) to the affected area precisely without destroying normal tissues. However, it is difficult to apply HIFU precisely due to the motion of the affected area with the diaphragm contracts breathing. Therefore, the authors propose the integrated system which has the function to compensate for the influence of the respiratory motion by using the motion tracking technology. In this paper, the authors report configuration of the integrated system and experimental results on 3D tracking and destroying stone with the system and a kidney stone model.
