    The Dome CXtra software adds essential functionality to Dome medical imaging display systems in diagnostic and referral settings. By using the Dome CXtra suite of value-added services, you can calibrate and maintain displays, run acceptance tests, and monitor displays remotely. While the services operate as independent plug- ins, they each use the Reporting service for listing properties, logging events, and saving history.
