Abstract
A technique is provided for improving performance of a digital detector system, such as in a digital X-ray system. Improved frame rates and enhanced resolutions are achieved by selecting a field of view of interest and processing pixel information only for the selected field of view. Data from a series of rows of the detector are simultaneously processed by restoring charge to pixels of a row, while digitizing signals from a previously recharged row, and transmitting digital signals for a third row for which the signals were previously digitized. Scrubbing of rows outside the selected field of view may be performed as signals are detected and processes for rows within the selected field of view.
