Use of a robotic arm to perform remote abdominal telesonography

OBJECTIVE: The purpose of this study was to design and validate a method of performing sonography between an expert center and an isolated site. A sonography probe is held on the patient by a robotic arm and remotely controlled from the expert's center. The robotic arm reproduces all the movements of the expert's dummy probe on the patient probe. The system was tested on 87 patients at our hospital. CONCLUSION: Robotic telesonography can be used for reliable diagnosis without moving the patient. No false diagnoses were made in this study. A bandwidth of 250 Kbps via integrated services digital network or satellite is required for reliable diagnosis. Such a system can provide diagnostic information that is currently unavailable in isolated or inaccessible areas and on rescue vehicles.
