Regional Medical ArchivesHUBS is developing NGI technology to integrate dispersed regional medical facilities into an integrated "virtual hospital" supporting intelligent archiving of medical images for patient care, collaborative research, medical education, remote mentoring, and shared laboratory resources. We have a team of four regional medical centers as a pilot, including the Johns Hopkins University School of Medicine (JHSoM), the University of Pittsburgh Medical Center (UPMC), the University of Medicine and Dentistry of New Jersey (UMDNI), and the University of Pennsylvania Health System (UPHS). To date, Computer-based Patient Records systems (CPRS), the current state-of-the-art in computer-supported health care, have avoided dealing with the storage, retrieval, and display of image data because of the voluminous and complex network traffic and overwhelming performance burden. We intend to demonstrate the ability of clinical systems to take advantage of primary image archives, which will open the door for huge amounts of data currently not readily available to physicians. This includes patient radiographs, EKGS, spirograms, endoscopy images, and even videos of important procedures. Radiology and pathology are the two specialties providing the bulk of diagnostic image-based data. They are among the most digitally advanced and computer-savvy specialties in medicine. Together, they will provide a potent application demonstration test bed. Using the NG-VPN, we will create a distributed, low-latency, fault-tolerant, secure, scalable, hierarchical, client-server, multi-terabyte storage system and high performance software meeting the requirements including transparency, confidentiality, authorization, consistency, flexibility, replication, and completeness. Regional archives will be established at the Pittsburgh SuperComputing Center to take advantage of its existing infrastructure. Through this architecture, we will provide a very high throughput, very low latency connection between each institutions primary archive or its archival database. Each will be created with the objective of maximizing the concordance between the archive and production databases and the ability to transfer production to the secondary archive in event of a localized failure.
