Abstract

Multimedia including the Internet has been utilized in various situations, especially in the educational and medical fields. The concept of a space collaboration system was developed by the Ministry of Education and Educational Broadcasting Center three years ago. The first such system in Japan was completed in October 1996. This space collaboration system is also called an inter-university network using a satellite system. The objective of this system is improving higher education in a multimedia society using the interuniversity network. Characteristics of the satellite system are worldwide broadcasting and simultaneous transmission to numerous locations. Both transmission and reception could be achieved simultaneously using this system. However, this system is very expensive and requires highly trained technicians for broadcasting. Currently, specialists and licenses for broadcasting are also required for this broadcasting system. In this system, a VSAT (Very Small Aperture Terminal) system was accepted, thus we could transmit and receive images and data easily by ourselves. We used this system for a case conference on radiation therapy between Osaka University and Hokkaido University. Required materials for the conference on radiation therapy were printed material, diagnostic images, pictures, speaker's voice and face, and audience. Printed materials included the patient's chart, treatment plan, and irradiation records. Images consisted of transparent film, such as CT and MR images, as well conventional radiographs. There were three kinds of cameras used in this system. One was a CCD camera for the speakers and listeners. Another camera for reflective light was used for printed material. A third camera for transparent light was used for the images. It was found that we could easily transmit and receive high resolution images, and real time images were transmitted and received simultaneously. However, we must point out the rather high expenses, and the limitation of time and facilities as disadvantages.
