2A1-A18 The development of the integrated system for non invasive ultrasound diagnosis and treatment (1st report) : The controller and experiment for servoing stone model in the bladder

Abstract

In this paper, the authors report the required functions of the integrated system for non invasive ultrasound diagnosis and treatment and the methods of mounting these functions. The concept of the proposed system is to destroy cancer tissues and stones by applying high intensity focused ultrasound (HIFU) to the affected parts precisely without destroying peritumoral tissues. But if the affected parts lie in the deep portion of the patient's body, it is difficult to apply HIFU precisely by reason of the movement of the affected parts with the influence of breath. Therefore the authors propose the system which has the function of canceling the influence of the movement.
