The quality of ultrasound based diagnosis highly depends on the operator's skills. Some healthcare centres may not have the required medical experts on hand when needed and therefore may not benefit from highly specialized ultrasound examinations. The aim of this project is to provide a reliable solution in order to perform expert ultrasound examinations in(More)
This paper presents a new tele-operated robotic chain for real-time ultrasound image acquisition and medical diagnosis. This system has been developed in the frame of the Mobile Tele-Echography Using an Ultralight Robot European Project. A light-weight six degrees-of-freedom serial robot, with a remote center of motion, has been specially designed for this(More)
This paper presents a new tool for the evaluation of ultrasound image compression. The goal is to measure the image quality as easily as with a statistical criterion, and with the same reliability as the one provided by the medical assessment. An initial experiment is proposed to medical experts and represents our reference value for the comparison of(More)
This paper presents a master-slave system applied to the remote diagnosis from echographic data. The motion of the master manipulator is remotely controlled by a physician and reproduced by a slave robot carrying the echographic probe. The contact force between the probe and the patient is fed back to operator allowing him to have a haptic virtual(More)
