Online OsiriX Documentation/Using OsiriX as a PACS workstation
Yes, you can use OsiriX as a PACS workstation! You don’t have to to buy multi-thousand $$ PACS workstation licenses! Save your bucks and buy Macintosh computers instead!
You only have to configure your modalities to automatically send exams to your OsiriX computer: configure the AETitle and Port number in OsiriX (see Importing DICOM images into OsiriX and Viewing DICOM headers).
Note: OsiriX website defines it self as a DICOM Client and explains how to get a free PACS system. It does not make it clear, however, what limitations OsiriX has over a PACS system.
