title: Uncompressed video image transmission of laparoscopic or endoscopic surgery for telemedicine.
abstract: Traditional narrowband telemedicine cannot provide quality dynamic images. We conducted videoconferences of laparoscopic and endoscopic operations via an uncompressed video transmission technique. A superfast broadband Internet link was set up between Shanghai in the People's Republic of China and Fukuoka in Japan. Uncompressed dynamic video images of laparoscopic and endoscopic operations were transmitted by a digital video transfer system (DVTS). Seven teleconferences were conducted between June 2005 and June 2007. Of the 7 teleconferences, 5 were live surgical demonstrations and 3 were recorded video teleconsultations. Smoothness of the motion picture, sharpness of images, and clarity of sound were benefited by this form of telemedicine based upon DVTS. Telemedicine based upon DVTS is a superior choice for laparoscopic and endoscopic skill training across the borders.
