Linear Accelerators


Providing superior cancer care starts with top-notch equipment. Refurbished linear accelerators from R.O.S.  (Radiology Oncology Systems) offer a high-quality alternative without the high cost of new equipment. That leaves additional funding for other types of patient care while still ensuring the best radiation treatment for certain health needs.

A LINAC (linear accelerator) is a must-have for any radiation oncology care provider.  Approximately 60 percent of all cancer cases in the U.S. involve some form of radiation therapy, and recent technological improvements by linear accelerator manufacturers allow for unprecedented accuracy and safety in treating tumors, and limiting effects on the surrounding normal tissue.

Care providers are able to get affordable-yet-effective linear accelerators for radiation therapy by purchasing their equipment from Radiology Oncology Systems. R.O.S. offers a choice of four refurbishment packages, making it easy to stay within budget while still getting equipment that is reliable, safe and effective. Regardless of refurbishment level, every linear accelerator from R.O.S. goes through a meticulous inspection process. Testing, which is completed by experienced engineers, is rigid and thorough to ensure that each LINAC is in excellent working condition.

Purchasing linear accelerators for radiation therapy from Radiology Oncology Systems ensures an all-in-one comprehensive solution. Once you've selected your preferred equipment, you'll be presented with your choice of installation and warranty plans to accommodate your needs. We can arrange for the relocation, removal and/or disposal of your existing LINAC and provide dedicated project planning and logistics.

Don't let the lack of proper working equipment interrupt your ability to provide the best care for your patients. Turn to Radiology Oncology Systems to find tested, preowned linear accelerators and other high-quality radiation therapy equipment from top brands like Varian, Elekta and Siemens. We'll help you find the perfect fit for your needs so you can focus on providing effective, quality care.
