ABSTRACT
Investigation on the applicability of low-cost videoconferencing (VC) for health care services is becoming a real need. Reduced resources drive the administrators to evaluate inexpensive solutions for telemedicine. Considering this scenario, this work is a preliminary step to validate, from a technical point of view, if low-cost VC systems could be suitable for orthopaedic teleconsulting services. For this purpose, four different videoconferencing systems were tested. Each VC system was composed of a computer and a VC device installed in. VC devices were chosen among the most popular and distributed products (made by Intel, PictureTel and Aethra). The Telemedicine Benchmark, a specific tool defined by the authors, was applied to measure the overall systems performances in terms of time delays during basic rate ISDN connections (128 Kbit/s). Results showed that it is possible to apply low-cost videoconferencing systems for orthopaedic teleconsulting services. Most of the systems provided acceptable performance for medical image visualization and real time joint working. Further developments are recommendable to enhance the VC software tools capabilities and to improve software-user interface. reserved.
