摘要： An energy discrimination radiography system includes at least one radiation source configured to alternately irradiate a component with radiation characterized by at least two energy spectra, where the component has a number of constituents. At least one radiation detector is configured to receive radiation passing through the component and a computer is operationally coupled to the detector. The computer is configured to receive data corresponding to each of the energy spectra for a scan of the component, process the data to generate a multi-energy data set, and decompose the multi-energy data set to generate material characterization images in substantially real time. A method for inspecting the component includes irradiating the component, receiving a data stream of energy discriminated data, processing the energy discriminated data, to generate a multi-energy data set, and decomposing the multi-energy data set, to generate material characterization images in substantially real time.

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： 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.
