2A1-R08 Calibration of the ultrasound probe for position control of ultrasonic imaging plane by the robot(Medical Robotics and Mechatronics(2))

Abstract

Since ultrasonic diagnostic equipment is small and cheap compared to CT or MRI, 3D-information acquiring methods by ultrasound (US) are widely studied. For that purpose, identification of the spatial relationship between an US probe and a position measuring device is required. Many methods have been proposed, but there is little research taking into consideration the thickness of the cross-sectional image. In this study, we propose a cross-sectional image position identification method taking into account the section thickness. Additionally, we performed an experiment to assess the accuracy of our method. We observed that it is simple and accurate.
