Open the CIPO recordAbstract From the Canadian patent
Imaging tumors using diffuse light. An imaging system includes a source (35) of diffuse light for generating oscillatory diffuse photon density waves to illuminate an object (10) a detector (60) for detecting diffuse photon density waves interacting with the object and a computer (130) interfaced with the detector for processing data corresponding to the photon density waves detected to determine at least a position of the object. In one embodiment the turbid medium (20) and the object have associated therewith at least one diffusion coefficient and the diffuse photon density waves which illuminate the object refract around the object as a result of their interaction with it thereby …

Why it's free to use
- Filed October 31, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 31, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 31, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
