Is the Osimis orthanc FDA approved in the US? At least here I can't get anyone to even consider it w/o FDA approval for diagnostic purposes. I keep trying to convince my hospitals that it would be well worth pushing through the FDA clearance ourselves since it would save us XXX millions of dollars on PACS service contracts. :(
Rok, if you are looking for scalability numbers, I had about 15TB of mostly CT studies in Orthanc at my previous institution with no particular problems. (Other than not being able to use the old the web interface that tried to show you every patient in the database when you opened it up -- since fixed, thank you, Sebastien!). If anything it was faster and more stable than our real PACS, but that was probably b/c it wasn't accessed nearly as aggressively as the clinical system was.
