Our Centricity site has been waiting to upgrade from version 2.x to 3.x for a while. We had an intermediate upgrade recently, but we're still in the 2.x's. The PACS administrator was just informed that (surprize!) the jump to 3.x will require new hardware, because the new back-end uses Linux.
This isn't a total shock, really, given the fact that GE uses Linux in other products, such as the Advantage Workstation (the beloved AW), as well as within the consoles of several scanners. Not only is Linux cheaper than Windows (they use the Red Hat flavor), but it is more robust as well. It is reasonable for them to do some back end migration to this platform, especially since at one time or another, there has been everything from Sun Unix to Mac OS bundled in there somewhere.
Ah, but here is the problem we face. At this point, we don't know how much this hardware upgrade is going to cost. AND, we aren't really all that sure how long the Centricity product will continue, given the recent acquisition of Dynamic Imaging and the incorporation of its IntegradWeb program. At some point, depending upon how much hardware (and software for that matter) the upgrade will require, the balance sheet tips in the favor of simply replacing the old Centricity 2.x with the new IntegradWeb. I'm hoping that migration of several years of data from on to the other won't be a big problem. If it is, there really might not be a reason to upgrade at all, except to keep the whiney radiologists happy. And eventually, there might not be a reason to migrate within the GE family altogether.
Anybody out there know any details about these upgrades and migrations? I suppose GE will tell us sooner or later.....
