Open the CIPO recordAbstract From the Canadian patent
Process for the reconstruction of three-dimensional images of an object with the aid of measurements performed by bidimensional arrays of sensors on a succession of incidences around the object. There are at least two circular coaxial paths (2,2') on which the arrays (4,4') are displaced. Thus, it is possible either to accelerate the taking of images, or increase the volume of the measurements, or accelerate the calculation of the reconstructed image through the use of a single reference frame in whose coordinates the sums of the measurements on each sensor are characterized. Application to medical imaging o} to the non-destructive inspection of parts in emission or radiation attenuation …

Why it's free to use
- Filed November 26, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 26, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 26, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
