Abstract
Objective Measure the performance of self-developed Interoperable teleradiology system at various communication conditions.Methods Through three different network media (satellite network, Asymmetrical Digital Subscriber Loop (ADSL), and Shanghai health system′s private broadband WAN), Digital images in radiology were transmitted and experiments on teleradiology consultation were applied.Resultssuch as transmission time were recorded,effects of real-time consultation were evaluated subjectively,and experimental data were analyzed。Results In satellite network, time spent on the transmission of images is long and effects of consultation is normal; in broadband network, time spent is short and no delay is observed in interoperation.Conclusion teleconsultation can be hold on image sets composed of small matrix size images and compressed large matrix size images in satellite narrowband network, optimum transmission bandwidth is 192 kbps; original large matrix size images such as CR can be transmitted through broadband network and be used in teleconsultation.Real-time interoperation of the system doesn′t require very high bandwidth.It can be implemented at various communication conditions.
