CNT Technology

Micro-X – A Leading Technology Developer

Micro-X, a technology based, product manufacturing company focussed on global medical and security markets has developed world-leading, proprietary technology for miniaturising x-ray sources. Micro-X’s patented carbon nanotube (CNT) emitter technology inside the x-ray tube breaks through historical limitations of CNT x-ray technology ensuring stable, robust and high-powered CNT x-ray tubes. This technology has the potential to revolutionise the use and applications of x-ray imaging across the world and will be used as the platform for all Micro-X’s future product developments. Micro-X’s technology is supported by a highly skilled team of scientists, engineers, production technicians and management.

World First – A New Era In X-Ray

X-ray tubes really haven’t changed since Willhelm Röntgen x-rayed his wife’s hand in 1895; they all use a heated filament like the old-fashioned incandescent light bulb to generate electrons inside a vacuum tube to create x-rays. The hotter the filament, the more electrons you get and the more x-rays you get.

Micro-X is the first company globally to bring a medical product to market using a digital x-ray tube with a cold electron source material, simply controlled by a small voltage. The first production carbon nanotubes were fitted into the DRX-Revolution Nano, launched in 2018 and sold through Carestream.  Micro-X’s X-ray tube technology enables smaller, lighter, faster, and more precisely controlled imaging systems to be developed and brought to medical and security markets.

Micro-X has created its own proprietary intellectual property around both the CNT emitter and the method of manufacture. This game changing technology delivers:

  • Long stable life with no degradation in electron current performance over at least 5 years of multiple daily exposures
  • High current with a maximum emitter current of 130mA for up to 2 seconds
  • Simple, scalable, and repeatable fabrication processes

Thinking small is big

The precise and instantaneous electronic control of Micro’s X-ray tube technology opens up a world of opportunities. This technology allows us to drive the size of x-ray imaging equipment smaller and smaller offering customers new ways and new uses of x-ray imaging. But the most exciting new applications involve arrays of miniature x-ray sources which can be electronically switched in sequence to produce a moving x-ray beam from stationary components. Conventional CT scanners rotate a giant x-ray tube quickly in a gantry to scan patients; Micro-X’s technology can do this with no moving parts. The CNT emitter and x-ray tube technology developed and manufactured in Adelaide by Micro-X indeed ushers in a new era in X-ray.

Micro-X has published a white paper providing an overview of their patented CNT emitter technology, breaking through historical limitations of CNT x-ray technology and demonstrating the stable and long-life performance of Micro-X’s CNT x-ray tubes’.
