    • A computed radiography system is provided. The computed radiography system includes an imaging plate configured to store a radiation energy pattern of an object or emit multiple prompt emission photons of the radiation energy pattern upon irradiation or a combination thereof. The computed radiography system also includes at least one light source configured to illuminate at least a sub-area of the imaging plate for a time period of less than about a second. The at least one light source is configured to stimulate at least one of an emission of multiple photons of the radiation energy pattern stored in the imaging plate. The computed radiography system further includes a two dimensional imager configured to capture at least one two dimensional image from the at least a sub-area of the imaging plate using one of an image emitted from the radiation energy pattern stored or an image emitted from prompt emission or a combination thereof.

    • A method and program product for real-time correction of non-functioning pixels in digital radiography, where the method comprises: receiving a list of non-functioning pixels; determining which neighboring functioning pixels are needed to correct the non-functioning pixels; organizing those neighboring functioning pixels and corresponding non-functioning pixels into a plurality of groups by a number of pixels used to perform correction; and performing correction of data from non-functioning pixels within one of the plurality of groups and subsequently performing correction of data from non-functioning pixels within another one of the plurality of groups. Also, a method and program product for producing an accurate real-time map of non-functioning pixels in a detector panel for digital radiography, where the method comprises: determining a first list of non-functioning pixels found using an extended exposure mode of the detector panel; determining a second list of non-functioning pixels found using a real-time mode of the detector panel; and merging the first and second lists into a merged list of non-functioning pixels for the detector panel.

    • An x-ray imaging device includes a borescope and an x-ray detector positioned at a distal end of the borescope. The x-ray detector can be configured to be movable into and out of an optical path and can include a scintillation screen. The movably configured x-ray detector can be moved into the optical path, when x-rays are impinging, and out of the optical path, when a visible image of a test object is desired, facilitating navigation of the x-ray detector through a test object. The x-ray imaging device can include an imager, for converting an image to an electronic format. The imager can be positioned at the proximal end of the borescope, with the borescope including a waveguide, for guiding light to a proximal end thereof. Alternatively, the imager can be positioned between the distal end of the borescope and the x-ray detector.
