RadParts

RadParts is a commercial-stage healthcare equipment company focused on the radiation oncology aftermarket. It supplies OEM replacement parts, accessories, consumables, and repair support for linear accelerators, radiotherapy CT simulators, and related radiation oncology and radiography equipment. The company positions itself as a large independent distributor in this niche and maintains a substantial inventory of linac components such as RF drivers, klystrons, magnetrons, waveguides, MLC motors, and power supplies. In September 2025, RadParts was acquired by Radiology Oncology Systems, bringing RadParts' replacement-parts business together with ROS's refurbished radiation oncology and diagnostic imaging system offerings. The business serves providers globally with cost-focused support intended to extend the usable life of installed radiation therapy equipment.
