March is Brain Injury Awareness Month

It is estimated that 69 million people worldwide suffer a traumatic brain injury (TBI) each year.


Although it is hard to imagine diagnosing brain injury without CT, that was the case prior to 1974, when the first clinical CT scanners were installed. These first CT systems were head-only, and they quickly changed brain injury diagnosis. In fact, by 1978, pneumoencephalography was virtually eliminated and use of nuclear medicine for brain scans was greatly diminished.
Today, CT is often the first imaging modality used to assess skull fractures, brain bleed, and TBI. Dunlee has been part of the story since the beginning. Milestones include:

March is Brain Injury Awareness Month

  • 1971: First CT scan of a patient performed at Atkinson Morley’s Hospital (London, England). The scan was 30 minutes. Today, a scan takes no more than a few minutes.
  • 1979: Godfrey Hounsfield and Allan MacLeod Cormack win the Nobel Prize in Physiology or Medicine for their work on CT.
  • 1980: Dunlee launches the industry’s first 1.0 MHU CT tube.
  • 1989: Spiral CT, which enables scanning of an entire organ during a 20-30 second breath hold, leads the way to CT Angiography, among other developments.
  • 1989: Dunlee develops world’s first liquid metal bearing (LMB) tube, for undisturbed workflow and longer life than tubes with ball bearings.
  • 1998: All major CT manufacturers introduced multislice CT systems, shortening scan times.
  • 2012: Dunlee introduces a 2D laser-sintered tungsten anti-scatter grid, providing OEM customers with unprecedented design freedom.
  • 2017-2022: Dunlee releases CT product bundles with third-generation LMB tubes that support gantry rotation speeds up to 240 RPM.


All of us at Dunlee are grateful for the strides made in fast diagnosis of brain injury, and proud that we’ve played a part in that progress.


During this month dedicated to brain injury awareness, we extend a special thank you to our customers who have helped so many patients receive a fast and accurate diagnosis of brain injuries.
