LBT Diagnostic Radiation Physics Consulting LTD

LBT Diagnostic Radiation Physics Consulting LTD, a Service-Disabled Veteran-Owned Small Business (SDVOSB) and Veteran-Owned Small Business (VOSB) based in Las Vegas, Nevada, operates as a prime contractor delivering diagnostic medical physics and radiation safety services to federal healthcare agencies under SDVOSB and small-business set-asides, with all 142 recent awards as prime work and none as subcontractor.

The vendor's capability footprint is narrowly focused and deep: medical physicist surveys, radiation safety officer consultation, diagnostic imaging equipment acceptance testing, calibration verification, quality assurance program development, and regulatory compliance verification for CT, MRI, mammography, fluoroscopy, nuclear medicine, PET/CT, and dental radiography systems. Work is delivered at individual VA medical centers and military treatment facilities, with scope typically including annual inspections, post-repair testing, shielding design calculations, and quarterly or annual compliance audits against Joint Commission, American College of Radiology, FDA, and OSHA standards. Representative named work includes a $675,500 purchase order with Veterans Integrated Service Network 6 for medical physicist inspection services at Salisbury VA Medical Center in North Carolina (December 2022, SDVOSB set-aside); a $485,167 definitive contract with VISN 5 for medical physicist support at the Washington DC VA Medical Center and associated clinics (July 2024, SDVOSB set-aside); a $438,973 order with VISN 19 for medical physicist and radiation safety officer services at the George E. Wahlen VA Medical Center in Salt Lake City (April 2025, SDVOSB set-aside); and a $433,800 purchase order with VISN 21 for on-site medical physics support and MRI safety emergency consultation at the VA Las Vegas Medical Center (September 2026, no set-aside).

Customer concentration is extreme and centered on the Veterans Health Administration. The top five VISN offices account for 56% of awards by count and 58% of combined potential value, led by VISN 22 (35 awards, $2.9 million), VISN 21 (11 awards, $3.5 million), VISN 8 (12 awards, $2.1 million), VISN 15 (9 awards, $1.3 million), and VISN 6 (4 awards, $1.2 million). The vendor also maintains contracts with the Defense Health Agency (for medical physics testing at Army and Air Force medical facilities), the Indian Health Service (for medical physicist surveys at tribal facilities), and the Air Force Test Center. Of the 18 distinct customer agencies served, the VA accounts for the vast majority of volume and dollars; non-VA work is opportunistic, including single military treatment facility contracts and one-off IHS engagement.

LBT holds eight active single-award indefinite delivery contracts: $700,000 with VISN 16 for medical physicist inspections of imaging equipment in Arkansas (award July 2024, through July 2029); $675,500 with VISN 6 for medical physicist inspections at Salisbury VA Medical Center in North Carolina (awarded December 2022, through September 2027); $485,167 with VISN 5 for medical physicist support at Washington DC VA Medical Center (awarded July 2024, through July 2029); $449,594 with VISN 8 for diagnostic imaging survey services in Orlando, Florida (awarded January 2025, through December 2029); $438,973 with VISN 19 for medical physicist and radiation safety officer services in Salt Lake City (awarded April 2025, through March 2030); $434,400 with VISN 21 for radiation safety officer consultation in San Francisco (awarded April 2024, through March 2029); $340,000 with VISN 19 for Magnetic Resonance Safety Expert services at five VA medical facilities (awarded April 2026, through April 2031); and $219,490 with VISN 15 for medical physics testing at the Harry S Truman VA Medical Center in Columbia, Missouri (awarded September 2025, through September 2030). These eight vehicles carry a combined ceiling of approximately $3.8 million and represent the structural foundation of LBT's federal footprint — each is reserved for SDVOSB vendors and issues multiple delivery orders per contract year.

Activity has grown sharply: six awards in 2022, thirteen in 2023, twelve in 2024, twenty-two in 2025, and twenty-one through October 2026. However, twenty-three awards (combined potential value $2.8 million) face ultimate completion inside the next twenty-four months, presenting significant recompete exposure. The vendor competes almost entirely under SDVOSB and small-business set-asides; very few awards are issued full-and-open. NAICS concentration runs toward 541690 (Other Scientific and Technical Consulting Services, 63 awards) and 541714 (Testing Laboratories and Services, 53 awards), with PSC codes clustering on equipment maintenance and quality control for medical and dental systems.

Service Contract Inventory reporting captures minimal federal services activity: only one SCI-reported prime contract appears in the dataset, with $390 thousand in invoiced revenue in FY2025 across 1.1 FTEs. SCI is a strict subset of LBT's federal work and does not reflect the vendor's true revenue scale — the majority of the contract portfolio consists of purchase orders and delivery orders below or outside the SCI $150,000 threshold, and SCI excludes classified work. The vendor operates as a pure prime, bringing no named subcontractors to any of the awards in the source data, and across SCI-reportable prime contracts reports zero sub-hours engagement.

LBT's federal footprint is almost entirely confined to recurring medical physics and radiation safety services at VA regional networks, with shallow penetration into Defense Health Agency and Indian Health Service sectors. The business is structured around small-business and SDVOSB set-asides; the company does not appear to compete for full-and-open or higher-ceiling programs. Growth trajectory is positive, but recompete risk in the next two years is material at roughly $2.8 million of the $18.8 million total portfolio.
