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
Need for even better quality… • Telepathology • Telesurgery • PC presentation Transmission of HD quality should be tried
Menu for today • Telepathology with HDTV • What is pathology? • Surgical application • New surgical instrument • Possible solution for PC presentation? Kyushu Univ., Fukuoka
X-ray Resected specimen For making the final diagnosis Malignant or benign? How advanced?
Microsope Final diagnosis by pathology Magnified view
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
