A system for compensating for capacitively coupled artifacts in signals generated by a matrix-addressed x-ray imaging panel (15) including a matrix addressed array of sensing cells (116) connected to respective integrating read-out amplifiers (146). While all scan lines (117) are de-energized, a plurality of induced signals output by each amplifier (146) are read, accumulated and averaged by a processor (150) to form respective average values. During normal image panel (15) operation, while scan lines (117) are energized, processor (150) subtracts respective average values from image signals output by respective amplifiers (146). The result is rounded to obtain an integer value for an image signal corresponding to each amplifier (146) that is compensated for capacitively coupled artifacts.
