September 29, 2025 – Radiology Oncology Systems (ROS), the leader in refurbished radiation oncology and diagnostic imaging systems, is thrilled to announce the acquisition of Radparts, the world’s largest independent distributor of OEM replacement parts for linear accelerators. The announcement will be formerly presented at ASTRO 2025 in San Francisco occurring from September 27 through October 1, 2025. This strategic move unites two key industry players to deliver a seamless, turnkey experience for radiation oncology facilities worldwide, combining trusted replacement parts with complete refurbished systems under one roof. Radparts was formerly a unit of Catalyst MedTech.
By integrating Radparts’ extensive inventory of high-quality OEM replacement parts – including RF drivers, klystrons, magnetrons, MLC motors, power supplies, cables, and more – with ROS’s decades of expertise in delivering refurbished systems, the combined entity offers unmatched reliability and cost-effective solutions for radiation oncology providers, while also helping OEMs extend their reach and technology. This acquisition creates a “whole greater than the sum of its parts,” providing customers with a trusted source for their linear accelerator and other equipment needs.
“We are excited to welcome Radparts to the ROS family,” said John Vano, president of ROS. “This acquisition strengthens our mission to deliver world-class, comprehensive solutions that empower healthcare providers to focus on patient care with confidence in their equipment’s performance.”
“We are thrilled to join forces with ROS,” said Wendy Summers, Vice President of Operations at Radparts. “This partnership enhances our ability to serve customers by combining our extensive parts inventory with ROS’s expertise in refurbished systems, creating a one-stop solution for our customers across the globe.”
