Open the CIPO recordAbstract From the Canadian patent
A detector assembly for multi-modality PET/SPEC/CT scanners consists of a thin detector on top of one or more deep detectors to detect low-energy gammas and high-energy annihilation photons. The deep detectors provides depth-of-interaction information for 511 keV detection in PET while the thin front detector, that is essentially transparent to 511 keV and low-energy gammas is used for detecting X-rays. Low-energy gammas can be detected by the thin detector on top and/or by the second deep detector of the assembly.

Why it's free to use
- Filed November 6, 1998 and granted April 19, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 6, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 6, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
