摘要： A radiographic image capturing device includes the following. A two-dimensional array of radiation detectors generate electrical charges corresponding to a dose of incident radiation. A control unit reads the electrical charges discharged from the radiation detectors in a form of image data. The control unit has radiographic modes including a still image mode for still image radiography, a moving image mode for moving image radiography, and a continuous radiographic mode for reading the image data without distinguishing between the still image radiography and the moving image radiography. The control unit selects the continuous radiographic mode to sequentially read the image data when an instruction on performing the still image radiography or the moving image radiography is not sent from an external control device or a user or when the radiographic mode is unknown due to communication failure with the external control device.

摘要： Embodiments of methods and/or apparatus for a radiographic imaging system can include a radiographic detector including an image receptor to receive incident radiation and generate uncorrected electronic image data; a storage device to store calibration data at the detector, and a processor to generate calibration-corrected image data from the uncorrected electronic image data and the calibration data. The calibration-corrected image data can be further processed by the processor to perform image processing before transmitting a corrected image (e.g., DICOM image) to the radiographic imaging system. The detector can further include a display to display imaging system controls or the corrected image.
