Abstract: A broad-banded medical network was established between Korea and Japan using Digital Video Transport System (DVTS) over Internet protocol. We used Kyushu GigaPOP (QGPOP) (Japanese side), the Korea Advanced Research Network (Korean side), and the Korea-Japan Cable Network (international line). The teleconferences with real-time transmission of laparoscopic surgery, neurosurgery, and endoscopic examination were successfully performed. The bandwidth was 30 Mbps for a line of transmission and two lines of DVTS were utilized. The uncompressed moving image had the rate of 30 per second. The security software was also used to protect patient privacy. This international telecommunication using high-quality moving image is very helpful for the exchange of new medical techniques among different countries. Read more

Abstract: We have established a medical network between China, Japan and Korea with high-quality moving image with Korea-Japan Cable Network (KJCN), a submarine optical cable between Busan and Fukuoka. Broadcasting real-time surgery and teleconference with medical-quality videos with Digital Video Transport System (DVTS) were useful to learn surgical techniques and other medical procedures beyond the geographical border. In this project, we have conducted 22 events mainly between Korea and Japan in categories of teleconference (8 times), live transmission of medical procedure (7 times), and remote attendance to scientific medical meetings (7 times) until the end of Oct. 2004. On 12th Oct. 2004, we connected to Tsinghua University in Beijing, China, to have a first medical video teleconference with China in 5th Distance Learning and Internet in Association of Rim of University. With these experiences and current achievements, we hope to extend this advanced network system to whole Asia-Pacific countries to share medical skills and knowledge. Read more

Abstract: We have promoted the international telemedicine project with Digital Video Transfer System to transmit high quality moving images on TCP/IP in Asia-Pacific area since February 2003. We have used the canvas network in Kyushu University, domestic Giga-bit networks (JGN, JGN2, SuperSINET), and international Giga-bit networks (Korea Japan Cable Network, and lines of Asia-Pacific Advanced Network). We have three categories in the project, (1) regular teleconferences to exchange the opinion internationally, (2) live transmissions during operation procedure, (3) remote participation at international academic meetings. We have had total 46 telemedical events in Japan, Korea, China, Taiwan, Thailand, USA, and Australia until September, 2005. We are planning to extend the network to Singapore, Malaysia, and Philippine until 2007. The project can promote exchanges and standardizations of knowledge on the medical technique, social medical systems, medical ethics, new medical items, medical science, and medical education in Asia-Pacific Area.

Abstract: Background/Aims: Telemedicine has opened the door to a wide range of learning experience and simultaneous feedback to doctors and students at various remote locations, However, there are limitations such as lack of approved international standards of ethics. The aim of our study was to establish a telemedical education system through the development of high quality images, using the digital transfer system on a high-speed network. Methodology: Using telemedicine, surgical images can be sent not only to domestic areas but also abroad, and opinions regarding surgical procedures can be exchanged between the operation room and a remote place, The Asia Pacific Information Infrastructure (APII) link, a submarine cable between Busan and Fukuoka, was used to connect Korea with Japan, and Korea Advanced Research Network (KOREN) was used to connect Busan and Seoul. Teleconference and video streaming between Hanyang University Hospital on Seoul and Kyushu University Hospital in Japan were realized using Digital Video Transfer System (DVTS) over Ipv4 network. Results: Four endoscopic surgeries were successfully transmitted between Seoul and Kyushu, while contaminant teleconferences were taken place between the two throughout the operations. Enough bandwidth of 60Mbps could be kept for two-line transmissions. The quality of transmitted video image had no frame loss with a rate of 30 images per second. The sound was also clear, and time delay was less than 0.3 sec. Conclusions: Our experience has demonstrated the feasibility of domestic and international telemedicine. We have established an international medical network with high-quality video transmission over Internet protocol, which is easy to perform, reliable, and economical. Our network system may become a promising tool for worldwide telemedical communication in the future. Read more

Abstract: Objectives: To promote the exchange of knowledge and standardization of medical procedures and medical systems in the Asia-Pacific region, we established a medical network with high-quality moving images over broadband Internet lines in February 2003. Methods: Real-time teleconferences and live demonstrations with medical-quality videos, broadcast via the Digital Video Transport System, have been used to teach surgical techniques and other medical procedures across national borders. The Asia-Pacific Advanced Network (APAN) committee in August 2005 formally approved our proposal to establish a medical working group within APAN. The network was expanded by the launch of the Trans-Eurasia Information Network 2 in 2006. By the end of 2006, we had conducted 82 events, in 10 countries in the Asia-Pacific region. The multi-station event has increased every year. Results: There have been no serious transmission problems or ethical conflicts so far. With these experiences and current achievements, we hope to extend this advanced network system to the entire Asia-Pacific. Condusion: This system is a promising and very useful tool for the standardization of medical system and procedures across national borders. Drawing upon these experiences and current achievements, we hope to extend this advanced network system to the entire Asia-Pacific region. Read more
