Carestream completed the initial PACS installation across the country in 2009 and the upgrade is scheduled for completion in November 2013.
"PACS V11 will allow quicker treatment for our more urgent cases, as clinicians will be able to access other sites' images directly, " said Alan Fleming, PACS Project Manager at NHS National Services Scotland.
"Global worklists, tunnelling and streaming and push are added functions in PACS V11 which have widespread clinical support as developments.
"V11 PACS has a strong financial component for NHS Scotland by allowing development of sophisticated models for storage management and retention in the archive."
The latest Carestream Vue PACS V11 architecture provides significant enhancements in information sharing by consolidating data into a global workflow with a global worklist.
All authorised users have the ability to view on demand a patient's entire imaging history from anywhere in Scotland, regardless of where they were imaged.
Images are intelligently streamed and tunnelled through the fastest route available, speeding up access and distribution of images and associated information.
The upgrade to the National Archive will implement new compression, storage and retention plans according to the latest guidance from the Royal College of Radiologists, which will significantly reduce storage requirements and operational costs.
