Various vendors and professionals in the PACS
community have been cluttering the market with their own interpretations
of the definition of “Neutral” PACS. Here is my straight-forward
approach and hopefully bring a common understanding within the community
as to what being vendor neutral really means and benefits when looking
Common definitions of “Neutral”:
VEA –Vendor Enterprise Archive - PACS vendors
archive solution to store multi-ology/multi-department images. Like in
the past, software upgrades, new PACS or even storage system changes
with the VEA normally result in an expensive and time consuming data
migration of entire image repository.
VNA – Vendor Neutral Archive - A software
solution providing DICOM message translation, transformation, object
registry and routing services. It mediates the interoperability between
different brands of PACS solutions and clinical workflow applications.
It has been known as a PACS that integrates with a various storage
platforms and IT strategies. VNA supports one or many clinical viewing
applications, standards based environment, storage virtualization
strategies, robust business continuity deployments and virtual
I see “Neutral” as the freedom of Choice, Control and Flexibility to ensure data ownership.
For a long time it has been generally accepted that
the PACS vendor owns the archive and stores images in its preferred
format, typically in a hybrid format that is only readable by that
particular vendor. Figuring who better knows your VEA than your PACS
vendor? This scenario has been proven to lock customers into one
particular PACS vendor.
