Abstract
A radiographic detector acquires a first partial exposed image signal during an image readout of each of the rows of photosensors, one row at a time. A first scan of each row includes measuring the charge delivered to each cell of the rows, including some rows having partial charge and other rows having full charge, and obtaining a first null image signal during the scan. A second scan includes measuring remaining charge delivered to those rows having partial charge. The null image signal data is subtracted from a sum of the first two scans.
