背景：虽然电信越来越普及，但通过窄带网络发送的低质量图像限制了其在医疗领域的应用。方法：通过超高速宽带网络连接日本九州大学医院和韩国四家医院。采用的是能在不损失图像质量的情况下传输数字视频的数字视频传输系统，带宽为30mbps /线。结果：16次远程会议中，6次为实时内镜手术。除手术影像外，还传送了术前诊断影像、手术室影像、会议室工作人员影像，便于讨论。网络保持稳定，声音延迟控制在0.3 s以内。在其他10次电话会议中，使用录制的视频图像进行讨论。结论：建立了一套高质量、实用、经济、便于临床使用的远程会议系统。该系统显示了超越地理边界的远程教育的前景。
Background: Although telecommunication is increasing in popularity, poor-quality images sent through a narrowband network limit its use in the medical field.Methods: Kyushu University Hospital in Japan and four hospitals in Korea were linked via superfast broadband Internet connection. The digital video transfer system, which can transmit digital videos without loss of image quality, was used, and the bandwidth was 30 Mbps per line.Results: Of the 16 teleconferences conducted, 6 demonstrated real-time endoscopic surgery. In addition to the surgical images, preoperative diagnostic images, images of the operating room, and images of the staff in the conference room were transmitted to facilitate discussion. The network remained stable, and the sound delay was restricted to less than 0.3 s. In the other 10 teleconferences, recorded video images were used for discussion.Conclusions: The authors have established a high-quality, practical teleconference system that is economical and easy to use in clinical practice. This system shows promise for remote education beyond geographic borders.
