The Department of Veterans Affairs intends to award a sole source contract to Sun Nuclear Corporation for the procurement of a Sun Nuclear 3D Dosimetry Scanner, which is essential for enhancing the accuracy and efficiency of radiation dose measurements in radiation therapy. This acquisition is critical as the existing scanner has become obsolete and no longer qualifies for maintenance, necessitating a replacement to ensure compliance with national standards and patient safety. The contract will include delivery, installation, a 12-month warranty, and comprehensive maintenance services, with a focus on technical capability, response time, cost, customer support, and delivery timelines. Interested vendors must submit their responses by August 4, 2025, to Marcus Lewis at Marcus.Lewis2@va.gov, as this notice does not constitute a request for competitive proposals.
