Effectiveness of tele-echography system with and without robotics according to patient circumstances

We have developed two independent systems for tele-echography, which is a new diagnose method with distance between doctor and patient. They are based on the network communication of signal and image exchange. First we experienced the system with robotic technology with a diagnose robot in the patient side and a controller in the doctor side and the positional relationship between the probe and body surface. We also developed interface software of computer graphics (CG), which helped to evaluate delay time of signals through network. Making use of those experiences, we developed the secondary system without robotics, with augmented reality (AR), to reproduce the probe position and angle on GUI interface, which requires only an USB camera and two markers for the body. Through our experiences, we have confirmed effectiveness of robotic system in a fixed situation and non-robotic system in a domestic or emergency situation, respectively.
