13219 - NSI Sole Source Letter.pdf

This is a business letter from North Star Imaging Inc. (NSI) dated February 5, 2025, addressed to Morgan Nielsen at Hill Air Force Base regarding an NSI X5000 System (Serial Number 16101339).

The letter establishes NSI's role as the sole designer, engineer, manufacturer, integrator, installer, and performer of site acceptance tests for the NSI X-Series system. NSI emphasizes that the image acquisition and reconstruction software—including eFX-DR, View, and eFX-CT—are proprietary to NSI exclusively. Within the United States, NSI is the sole distributor of NSI equipment and the only company approved by NSI to install, service, and maintain the equipment and software. The letter highlights that maintenance and adjustment/alignment of the system requires intimate knowledge of the X-ray system, imaging components, and their control systems (hardware and software interface) as specifically configured for the X-Series system. NSI cautions that improper maintenance or unauthorized repairs could void the warranty and render equipment inoperative. NSI strongly recommends that all servicing of North Star Imaging equipment be performed by NSI factory-trained personnel to ensure optimal operating condition. The letter is signed by Patrick R. Carlson, Global Technical Services Manager for Digital Radiography ASNT L3.
