Approach Network speed Storage
Slower Expensive
Solution: Transient Storage at workstation.
Historic Distributed Model
Current Centralized Model
Two Layers Core. Workstation.
Thin Client Leveraging standards. Operating system and Web Browser Technologies.
Network speed and Bandwidth. Integration into other hospital applications. Auto-routing and pre-fetching of images not
required. Scalability.
Current Centralized Model
