Low-cost ISDN videoconferencing equipment for orthopaedic second opinions

Abstract

We validated the application of low-cost ISDN videoconferencing equipment for telemedicine. A telemedicine benchmark was designed and four different office video conferencing systems were evaluated, all using basic-rate ISDN connections (128 kbit/s). All the low-cost systems showed generally good or acceptable performance for clinical use. We also investigated the feasibility of videoconferencing for an orthopaedic second-opinion service. Eight point-to-point conferences were conducted to discuss real clinical cases by use of interactive sharing of medical images. The average duration of each session was 35 min. Encouraging results were obtained.
