An optical tomographic system wherein the localization of secondary emitters (3,4) within an object of interest (2) is determined using the temporal signatures (12A, 12B, 12C) of secondary emission arising from the object being illuminated by an external primary source beam (1) that is non-parallel such , as a cone beam (1), while the object is moving relative to said beam (1) in a controlled manner. A unique set of secondary emitter spots is localized within the object and, when combined with a computed 3D reconstruction (35) of the object from its primary cone beam projections creates an image of the , secondary emitters (3,4) in the object so as to enable quantitative …

Why it's free to use
- Filed May 2, 2003 and granted December 18, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 2, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 2, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
