Distributed Model

Centralized Model

Historic Distributed Model

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

Transitional Technology

Incorporate both the models Pre-fetching, routing and fast retrieval of

images. Multiple versions of workstation. Complex Architecture.
