  • Patent number: 8894280
    Abstract: Embodiments of radiographic imaging systems and/or methods can operate a digital radiography detector in a multiple modes, where characteristics such as an exposure integration time and dark images (e.g., number timing integration time, etc.) for first and second modes are different. The digital radiography detector can be coupled to a memory that can store a first set of one or more calibration maps for the first mode and a second set of one or more calibration maps for the second mode and a processor. In one embodiment, the processor can form a first calibration-corrected exposure image by modifying a first exposure image from the first mode using the first set of calibration maps and a second calibration-corrected exposure image by modifying a second exposure image from the second mode using the second set of calibration maps in combination with calibration maps for the first mode.

  • Patent number: 7832928
    Abstract: A method of forming an offset-corrected exposure image includes obtaining an initial exposure image and exposure metadata related to the initial exposure image. An intermediate offset-corrected exposure image is formed by obtaining one or more dark images associated with the initial exposure image and subtracting an averaged value of the one or more dark images from the initial exposure image. The offset-corrected exposure image is obtained by combining an offset adjustment map with the intermediate offset-corrected exposure image.

  • Publication number: 20090129653
    Abstract: A method for transferring data from a digital radiography receiver panel obtains, at the receiver panel, a full-sized set of image data that comprises a diagnostic image for a patient and at least one reference image for dark signal compensation. A wireless transmission channel between the receiver panel and a separate host processor is monitored to obtain a transmission performance measure. The obtained transmission performance measure is compared against a predetermined threshold value. The response to the comparison is either (a) processing at least some portion of the full-sized set of image data at the receiver panel to form a reduced-size set of image data, then wirelessly transmitting the reduced-size set of image data to the host processor; or (b) wirelessly transmitting the full-sized set of image data from the receiver panel to the host processor.

  • Patent number: 5267727
    Abstract: A system and method which compares document requirements to the printer capability and determines the best match therebetween. When a mismatch occurs, the system determines the best match between size, color, weight and type by determining a mismatch magnitude between the job paper requirements and the printer's paper capabilities or stocks. The paper with the lowest mismatch magnitude is designated. The system also determines the best match between the document requirements and the printer capability for stapling, folding, duplexing and stacking. The operator is given an opportunity to correct any mismatches and the best match is used to configure the printer for the job if the user has specified a best match print strategy.
