Connectivity security and performance of an NGI testbed for medical imaging a

摘要

Abstract: Tele-medical imaging applications require low cost, and high- speed backbone wide area networks (WAN) to carry large amount of imaging data for rapid turn around interpretation. Current low cost commercially available WAN is too slow for medical imaging applications, while high speed WAN is too costly. Internet2 or Next Generation Internet (NGI) emerges as a good candidate for tele-medical imaging applications because of its high speed and low cost. This paper describes the beginning of a three-year project on exploring the possibility of using NGI for medical imaging applications. Connectivity of a private ATM to the Internet2 is first discussed, followed by methods of preserving data integrity in the public networks. Two medical imaging applications in telemammography and interactive teaching of breast imaging are presented. A preliminary plan on methods of evaluating the performance of the NGI is followed. !12
