Open the CIPO recordAbstract From the Canadian patent
An apparatus and method for making corrected impedance images of the chest includes an impedance imaging data acquisition system (609,611) which acquires impedance imaging data of the chest, an electrocardiograph (618) which obtains electrocardiograph data of the patient and a data analyzer (616) which , analyzes the electrocardiograph data to obtain information about breathing parameters at the time the impedance imaging data was acquired. The data analyzer reconstructs, from the imaging data and the information about breathing parameters, at least one impedance image of the chest with reduced sensitivity to breathing parameters.

Why it's free to use
- Filed July 3, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 3, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 3, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
