The document outlines the architecture of Picture Archiving and Communication Systems (PACS), highlighting the need to consider both current and future challenges due to the dynamic nature of technology and organizations. It compares distributed and centralized models of PACS architecture, detailing aspects such as operational fit, scalability, and integration with other hospital systems. Additionally, it mentions various storage solutions like SAN, NAS, and CAS as part of the architecture's evolution.

2. Architecture
 It is logical and functional description of the
hardware configuration of the system.
 While planning PACS architecture both current
and foreseeable issues must be taken into
consideration.
 This is difficult because both organization and
the technology are never in static state.

4. Elements of architecture
Operational fit
Versatility
Scalability
Robustness/Fault Tolerance

6. Historic Distributed Model
 Approach
 Network speed
 Storage
 Slower
 Expensive
 Solution: Transient Storage at workstation.

7. Historic Distributed Model

8. 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.

9. Current Centralized Model

10. Transitional Technology
 Incorporate both the models
 Pre-fetching, routing and fast retrieval of
images.
 Multiple versions of workstation.
 Complex Architecture.
