Open the CIPO recordAbstract From the Canadian patent
A method for compensation for object motion during a scan especially an , magnetic resonance imaging (MRI) scan is provided. The method involves taking a first data set corresponding to a first focussed image and adding a number of data points to form a slightly higher resolution image. Possible motions can then be modelled on the added data points and the effect on the focussing of the slightly higher resolution image determined using appropriate focus criteria.

Why it's free to use
- Filed December 5, 2002 and granted August 21, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 5, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 5, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
