Background: A robotic arm was developed by our laboratory for tele-operated echography on patients in locations isolated from a trained sonographer. The objective of the study was to evaluate, over a 1-year period, the use of the robotic arm for telesonography performed by a sonographer located at the University Hospital (Tours, France) on patients in two isolated medical centers 50 km away linked via the Internet.Materials And Methods: A nonsonographer operator (physician or paramedic) located the ultrasound probe attached to the robotic arm over the appropriate acoustic window for the organ of interest by rolling the whole robotic arm and mechanical support across the floor.
