ImagingBiz: VNA rethinking concept:
- VNA should be interpreted as Vendor Neutral Architecture rather than Archive. An archive is just one component of what the VNA actually does.
- A neutral platform that can serve up information in a native format, regardless of the application you are using to view, manipulate, and manage the data.
- The facility may also already have the storage; if so, the VNA will be attached to existing storage - in the physical or virtual environment - as an appliance. It is storage agnostic.
- The flexibility, or neutral aspect of the solution, derives from its reliance on standards (rather than proprietary code) and the solution’s ability to store clinical data in their native formats.
- When it comes to DICOM and non–DICOM images, VNA flexibility can really come in handy. If we are going to store DICOM information, it will be in a DICOM format, but with non–DICOM information, the formats are similar to what we use every day, such as TIFFs, QuickTime movies, and MP3s. It increases performance and reduce the cost of the system. When you wrap non–DICOM data, it makes the data twice as big, so now, your storage cost goes up; the Synapse VNA stores everything in its native format.
