Large Flat Panel Detector (LFPD )

The FDA Office of Acquisition and Grant Services is conducting market research to identify sources capable of providing one large-area 2D X-ray flat panel detector for cone-beam CT and fluoroscopy imaging, with responses due May 12, 2026. No set-aside is anticipated at this stage; the small business set-aside determination will be made based on market research results.

The detector must support human-sized phantom development and testing with an active imaging area of at least 42.7 cm × 42.7 cm, pixel pitch not exceeding 170 μm, MTF of at least 50% at 1 lp/mm, and DQE of at least 70%. The unit must operate across 40–150 kVp energy ranges with frame rates of 25 fps (fluoroscopy), 30 fps (fluoro zoom if offered), 40 fps (CBCT projection), and 4 fps (radiography full resolution). Air cooling is required; operating temperature must span 19–49°C (or wider); and radiation tolerance must reach at least 2,000 Gy. Weight may not exceed 15 kg. Lag on the first frame must not exceed 3%.

Delivery shall include complete operational kit with all electronics, interfaces, cables, adapters, and documentation, plus minimum one-year warranty and one-year remote technical support. The FDA will accept brand-name or equivalent products meeting or exceeding all specifications. NAICS code is 334510 (Electromedical and Electrotherapeutic Apparatus Manufacturing) with a 1,000-employee size standard. Responses limited to 10 pages (excluding attachments and data sheets) in PDF or Word format should include company information, UEI/CAGE codes, SAM.gov registration, detailed technical capability statements with compliance matrices, delivery timelines, warranty terms, past performance references, and optional pricing.
