Open the CIPO recordAbstract From the Canadian patent
MRA data is acquired from a large region of interest by translating the patient to successive stations at which successive portions of the threedimensional MRA data set are acquired. Patient movement is chosen to track a bolus of contrast agent as it passes through the region of interest and a 3D acquisition is performed at a succession of stations. The order and shape in which k-space is sampled differs from station-to-station to achieve maximum image contrast.

Why it's free to use
- Filed November 4, 1998 and granted September 17, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 4, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 4, 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.
