What is the difference between a DICOM viewer vs a PACS system or RIS


I have installed OsiriX is my computer which is an open source DICOM viewer. I was wondering what would make this different from a PACS (Picture archiving and communication system) or RIS (Radiology Information System). How could OsiriX be incorporated into one of them?

Just trying to get a better understanding of this 3 apparently different but interrelated concepts.


Solution

  • The viewer is an application that allows you to look at images. The PACS is a server that stores the images (they often have an accompanying viewer). The RIS is a workflow/record system for scheduling the time for the scanners, managing appointments, storing reports, etc.
