In September 1995 the United States military conducted a demonstration project to provide live ultrasound video and diagnostic DICOM still images using GTE's asynchronous transfer mode (ATM) technologies over an Orion T-1 satellite link. Still images were frame-grabbed from a Diasonics ultrasound and sent to the ALI Wide Area Network system. A group of diagnostic images was then sent in DICOM 3.0 format over a virtual ethernet satellite link from Chantilly, Virginia to Dayton, Ohio. These images came across a DICOM gateway into the Medical Diagnostic Imaging Support (MDIS) System. Live video from the ultrasound was also routed through a CLI Radiance VTC over the satellite to a VTC in Ohio. The video bandwidth was progressively narrowed with two radiologists determining the minimal acceptable bandwidth for detecting test objects in a phantom. The radiologists accepted live video ultrasound at bandwidths as low as 384 kbps from the hands of an experienced ultrasonographer located hundreds of miles away. DICOM still images were sent uncompressed and were of acceptable image quality when viewed on the MDIS system. The technology demonstrated holds great promise for both deployed U.S. Military Forces and civil uses of remote radiology. Detailed network drawings and videotapes of the ultrasound examinations at the remote site are provided.
