Open the CIPO recordAbstract From the Canadian patent
Displacement values which indicate respiration phase are acquired along with each view of an NMR scan. Two or more such NMR scans are conducted and the deviation of each displacement value from a smooth reference curve is employed to measure the integrity of its associated NMR image data. The NMR image data from the separate scans are combined to reduce random noise and motion artifacts and the combination, is accomplished by weighting the data in accordance with its measured integrity.

Why it's free to use
- Filed August 16, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 16, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 16, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
