Document Type and Number:
Japanese Patent JP6643449
Kind Code:
B2
Abstract:
To allow display of images without reducing delays of image display and correcting the degradation of images at radiation detection.SOLUTION: A radiographic apparatus according to the present invention comprises: a radiation detection array having a plurality of pixels two-dimensionally arranged which detect radiation and store electric charges; and a plurality of scan lines for discharging the electric charges stored in the pixels. The radiographic apparatus includes: a reset scanning control unit for performing reset scanning during which electric charges stored in the pixels are sequentially discharged; an irradiation detection unit for detecting a start of irradiation based on electric charges discharged by reset scanning; an imaging control unit for performing control such that upon detection of the start of irradiation, the reset scanning is stopped and electric charges stored in the pixels by irradiation are read to obtain image signals; a generation unit for generating image data based on image signals from which are excluded the image signals from the pixels on which reset scanning is performed during irradiation; and an output unit for outputting the image data to an external device.SELECTED DRAWING: Figure 7
