Zusammenfassung:	An X-ray imaging apparatus includes an X-ray source, an X-ray imaging panel, and a controller. The controller includes an image processing unit that generates an inspection image in accordance with a data signal read from a thin-film transistor with the thin-film transistor supplied with a gate signal, a detection control unit that detects a dark-spot pixel from the inspection image, and a threshold correction unit that applies, to a gate of the thin-film transistor corresponding to the dark-spot pixel, a positive shift voltage that raises a gate-off threshold voltage of the thin-film transistor.
