Today, radiology information systems (RIS) are typically built using one of two architectures:
Each approach offers distinct advantages depending on workflow, infrastructure, and operational requirements.
In a client/server system, data is stored on a central server, with dedicated (“thick”) client applications installed on each workstation.
These systems are typically deployed within a local network, with multiple sites connected through secure network connections.
Web-based RIS platforms are accessed through a browser over the internet or internal network, using lightweight (“thin”) clients.
This allows users to access the system from virtually any location with appropriate credentials.
Both client/server and web-based RIS platforms can be effective when implemented correctly.
The best choice depends on factors such as:
Selecting the right RIS architecture is one of the most important decisions a radiology department can make.
Before choosing between a web-based or client/server system, consider the following:
A web-based architecture may be appropriate if:
A client/server architecture may be more appropriate if:
In many cases, the ideal solution is not strictly one or the other—but a system that combines the strengths of both approaches.
