The ROS Story

Radiology Oncology Systems was formed in 1997 with the goal of providing radiation oncology and diagnostic imaging facilities around the world with quality, cost-effective solutions.  Every year, we continue to discover more opportunities to place quality, used equipment in areas that otherwise could not sustain quality, healthcare facilities.  We continue to search for ways of breaking down the barriers that prevent patients from accessing the technology required for care.  We support every clinician who seeks to expand the reach of medical care to areas that would not otherwise support it.
