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.

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.

  • Thank you! I am trying to develop an application that has some interaction (sends and receives information) with these systems. From what you mention it seems like I will need to setup both PACS & RIS. Are there any open-source setups? Can I used OsiriX as the viewer for an Open-Source PACS, or is this integration better done by the vendor/distributor? Should I just focus on finding an open-source PACS software with a good DICOM viewer? – BluePython May 05 '13 at 14:08
  • @Prussian I don't directly use RIS systems, so I can't comment there. We do however often use dcm4chee as an open source PACS system. I has an associated web viewer. There are a few libraries (open source and commercial, some better than others) that you can use if you need to develop an application that interacts with a PACS (in no particular order: RZDCM, Lead Tools, Clear Canvas, GDCM, mdcm, fellow oak dicom, dcmtk, DVTK, MyDICOM). – denver May 05 '13 at 21:41

OsiriX have both options means - Storage and viewer basically called Osirix was PACS but stand alone. Every PACS has its own viewer now a days either server client basis or web viewer. Dicom work station was different and PACS viewer was different.

RIS was Radiology information System which contains Process of Radiology dept. Scan orders > scheduling > Generating Modality work list > scan reports > Modality reports > MIS reports > Billing (Optional) > Radiology reporting > Reports dispatch > Sending reports to PACS etc.
IT will communicate with PACS through HL7. PACS and RIS should be two different servers but some are available both in same then it wont suitable for bigger workflows.
