A line scan imaging system incorporating a source of ionizing electromagnetic radiation, such as X-rays or gamma rays which use an improved microstrip gas counter as a detector. The microstrip gas counter detector provides very high efficiency to detect essentially all the incident radiation and a simple and, reliable inherent capability to discriminate and quantify the energy of the incident radiation. Thus the microstrip gas, counter detector provides colour images at low cost and complexity. The system may be used in a wide variety of applications including digital radiography computed tomography, food inspection and grading printed circuit board assembly, inspection wood processing, …

Why it's free to use
- Filed July 9, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 9, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 9, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
