A multiple mode digital X-ray imaging system providing for preprocessing "binning" of analog pixel signals from a detector array by selectively summing, within the detector array adjacent pixel charges on a , row-by-row basis and selectively summing within detector, array readout circuits the previously summed pixel charges (by rows) on a column-by-column basis. An array, or mapping of "defective, pixel" flags is used to identify defective pixels within the detector array with such flags being added to, or inserted into the incoming, data stream for dynamic processing along with the incoming pixel data. A buffer and filter is used to perform still image capture during the radiographic …

Why it's free to use
- Filed November 26, 1997 and granted April 23, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 26, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 26, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
