摘要： A method, system and apparatus for processing a radiographic image of a scanned object is disclosed. A pixel offset correction is performed in integer format on the radiographic image using saturation arithmetic to produce an image in integer format with any negative corrected values clipped to a value of zero. The resulting pixels are converted to floating point format and the converted pixels are multiplied by a gain factor. Optionally the resulting pixels are recursively averaged with previous results. The resulting pixels are converted to integer format and the converted pixel values are clamped to a maximum value using saturation arithmetic. Non-functional pixel correction is performed in integer format and the resulting pixel values are clamped to a maximum value using saturation arithmetic. An optional processing path replaces the recursive average by a linear average. The resulting pixel values are optionally filtered to enhance features of interest. The resulting pixel value is mapped in integer format to a palette index to establish an output pixel intensity having one of many intensity levels. The optional processing is controlled through the hardware interface of a real-time image controller as images are acquired.

摘要： A system and method for radiographic inspection of airfoil structure on aircraft includes a radiation source located on one side of the airfoil structure and an X-Y scanning device located on an opposing side of the airfoil structure. The X-Y scanning device is positioned to receive radiation from the radiation source. A radiation detector is mounted on the X-Y scanning device so as to be moveable relative to the airfoil structure along t two mutually orthogonal axes. In operation, the radiation detector is moved in a predetermined raster pattern while the radiation source is emitting radiation. This allows a large area to be inspected with single positioning of the X-Y scanning device, thereby improving throughput. The radiation detector converts impinging radiation into electrical signals, and a computer system processes the signals to generate radiographic images of the airfoil structure.

摘要： Intra-detector scatter correction methods to improve X-ray images. The method of correcting an X-ray image includes: receiving an original two-dimensional X-ray image; calculating a theoretical scattered image for a array of detector pixels by generating a theoretical point spread (TPS) function of a single pixel for a single line array of detector pixels, based on a system parameter; aggregating the TPS function into a full rotation of line arrays, so as to generating a TPS function for a 2-dimensional array of pixels; and applying the TPS function for a 2-dimensional array of pixels to a plurality of pixels in the detector; and then subtracting the theoretical scattered image from the original two-dimensional X-ray image, so as to create an improved X-ray image.
