Open the CIPO recordAbstract From the Canadian patent
A method of imaging a spatial distribution of a noble gas by nuclear magnetic resonance spectometry includes detecting a spatial distribution of at least one noble gas by NMR spectometry and generating a representation of said spatial distribution of the noble gas. The noble gas is selected from noble gas isotopes having nuclear spin preferably Xenon-129 and/or Helium-3. The noble gas is at least thermally or equilibrium polarized and is preferably hyperpolarized most preferably hyperpolarized by optical (laser) pumping in the presence of an alkali metal or by metastability exchange. The generation of the representation of the noble gas spatial distribution includes at least one dimension, …

Why it's free to use
- Filed April 4, 1995 and granted May 28, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 4, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 4, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
