  1. Topics on 10G applications in telemedicine:Transmission of High-Definition images Shuji Shimizu Naoki Nakashima Koji Okamura Kyushu University, Fukuoka, Japan

  2. Korea-Japan Medical Network Kyushu-Univ. Korea APII Gigabit Network Digital Video Transfer System DVTS DVTS Digital Video Transfer System • No compression of images • Minimal time delay

  3. Need for even better quality… • Telepathology • Telesurgery • PC presentation Transmission of HD quality should be tried

  4. Menu for today • Telepathology with HDTV • What is pathology? • Surgical application • New surgical instrument • Possible solution for PC presentation? Kyushu Univ., Fukuoka

  5. X-ray Resected specimen For making the final diagnosis Malignant or benign? How advanced?

  6. Microsope Final diagnosis by pathology Magnified view

  7. What we need for telepathology is … • Very high-resolution!!! HDTV quality should be mandatory. • Moving image is required. To examine all the fields on site Kyushu Univ., Fukuoka

  8. Image of telepathology between Korea and Japan Seoul Kyushu-Univ. Hyeonhae-Genkai GigabitNetwork DVTS DVTS HDTV HDTV DVTS is not satisfactory in quality.

  9. HTDV equipments for pathology Panasonic NTT Ikegami

  10. High denisity Telepathological System SONY HDC-X300 (HD-SDI) Fujitsu IP-7500 Olympus Microscope

  11. Menu for today • Telepathology with HDTV • What is pathology? • Surgical application • New surgical instrument • Possible solution for PC presentation? Kyushu Univ., Fukuoka

  12. Change in surgical instruments… • Analog to digital Recording: SVH to DV or DVD Direct digital output • DV to HD HD model in process Huge market is moving toward High-Vision instruments.

  13. 1 2 3 ◆ Improvement in surgical instruments Presentation method-3 Live surgery HD D/A Analog DV DVTS IE1394 S-VHS DV HD

  14. Olympus HTDV equipments for surgery Not commercially available yet

  15. Menu for today • Telepathology with HDTV • What is pathology? • Surgical application • New surgical instrument • Possible solution for PC presentation? Kyushu Univ., Fukuoka

  16. 5 1 HD? DV 2 • Quality • Speed • Movies 3 VNC IEEE1394 Even worse! ◆ Does HD improve the quality of PC presentation? Presentation method In-put method for presentation Loss of quqlity Twin Pact Analog DV DVTS IE1394 RGB 4 DV? HD?

  17. Multicast is necessary Hanyang University Hospital KIX Singapore 1G Seoul-XP 6M SEOUL Europe National Cancer Center 10M GSR USA 155M Seoul National Univ (Bundang Hospital) 155M TAEGU Ehwa Womans Univ GSR SUWON GSR GSR Seoul National Univ(Main Hospital) DEAJON Samsung Medical Center 2G GSR Japan BUSAN Chungnam National University GSR KWANJU Gyeongsang Univ Expected Connected Pusan University 1GMbps Subscriber

  18. Conclusions • There are strong needs and demands of High-Definition quality in telemedicine. • Telepathology and surgery are good candidates and ready for trial. HD may also be expected to improve the quality of PC presentation. • Multicast is strongly requested in telemedicine, which needs more bandwidth between KJ.
