NASA Documents the Birth of the Mini C-Arm Industry
NASA documentation detailing how LIXI technology evolved into low‑radiation fluoroscopy systems and helped launch the modern mini C‑arm industry.
NASA Technology Transfer
Part 4 of 5
Modern mini C-arm fluoroscopy systems trace their lineage directly to NASA’s early work in low‑intensity imaging. Between 1983 and 1991, NASA’s Spinoff publication documented a clear technological evolution.
1. Portable X-Ray Device (Lixiscope)
Publication: NASA Spinoff 1983

Subject: Aerospace Medicine
Distribution: Public (U.S. Government Work)
Summary
NASA’s 1983 Spinoff article introduces the Lixiscope (Low Intensity X-Ray Imaging Scope), a self-contained, battery-powered fluoroscope capable of producing instant X-ray images using only a very small amount of radioactive isotope. Originally developed at NASA’s Goddard Space Flight Center, the device was licensed to Lixi, Inc., which began commercial production for industrial inspection applications.
The Lixiscope’s design emphasized portability, minimal radiation exposure, and real-time imaging, making it suitable for field use and early medical evaluation scenarios. NASA noted that although the device was initially used for industrial inspection, it held clear potential for future medical applications.
Significance
The Lixiscope represents the first major NASA spinoff in low-intensity X-ray imaging and serves as the proof-of-concept for all subsequent compact fluoroscopy systems. Its innovations established the core engineering principles that would later define the mini C-arm industry.
2. X-Ray Imaging System (FluoroScan)
Publication: NASA Spinoff 1986
Source: Goddard Space Flight Center
Subject: Instrumentation and Photography
Distribution: Public (U.S. Government Work)
Summary
The 1986 Spinoff article documents the development of the FluoroScan Imaging System, a high-resolution, low-radiation X-ray device derived directly from NASA’s Lixiscope technology. The system was refined and commercialized by FluoroScan Imaging Systems, Inc. (formerly HealthMate, Inc.).
FluoroScan’s major components included:
- An X-ray generator
- A scintillator
- A visible-light image intensifier
- A video display
The system was small, lightweight, and maneuverable, enabling real-time imaging for:
- Fracture diagnosis
- Catheter placement
- Veterinary medicine
- Industrial inspection
Significance
FluoroScan represents the first true commercial implementation of NASA’s low-intensity imaging technology. Functionally, it is the earliest recognizable ancestor of the modern mini C-arm, bringing compact fluoroscopy into clinical environments for the first time.
3. X-Ray Imaging System (InnerView)
Publication: NASA Spinoff 1991
Source: Goddard Space Flight Center
Subject: Quality Assurance and Reliability
Distribution: Public (U.S. Government Work)
Summary
The 1991 Spinoff article describes the Model 60007A InnerView Real-Time X-Ray Imaging System, produced by National Imaging Systems, a division of FluoroScan Imaging Systems, Inc. This system is identified as a third-generation spinoff from NASA’s X-ray research.
NASA’s documented lineage is explicit:
- Goddard Space Flight Center develops the original low-intensity imaging technology for space applications.
- This technology becomes the Lixiscope, a portable, minimal-radiation X-ray instrument.
- FluoroScan Imaging Systems adapts the Lixiscope into the FluoroScan, a low-intensity clinical imaging system that does not require lead aprons, film badges, or lead-lined rooms.
- The InnerView system emerges as a further refinement, used in non-destructive testing, product inspection, and medical imaging.
Significance
The InnerView article is the clearest and most authoritative confirmation of the NASA, Lixiscope, FluoroScan, and modern fluoroscopy lineage. It highlights the breakthrough achievement: radiation levels low enough to eliminate the need for heavy shielding, enabling compact, mobile imaging systems.
About NASA Spinoff
Since 1976, NASA’s Spinoff program has documented technologies that originated from NASA research and later entered the commercial marketplace. These innovations span consumer electronics, medical devices, materials science, imaging, and countless other fields. Many everyday technologies — from memory foam to cell phone camera sensors — trace their origins to NASA investment.
NASA publishes dozens of these success stories annually, demonstrating the broad societal value of America’s space program.
