摘要： A system and method for ascertaining the identity of an object within an enclosed article. The system includes an acquisition subsystem, a reconstruction subsystem, a computer-aided detection (CAD) subsystem, and an alarm resolution subsystem. The acquisition subsystem communicates view data to the reconstruction subsystem, which reconstructs it into image data and communicates it to the CAD subsystem. The CAD subsystem analyzes the image data to ascertain whether it contains any area of interest. A feedback loop between the reconstruction and CAD subsystems allows for continued, more extensive analysis of the object. Other information, such as risk variables or trace chemical detection information may be communicated to the CAD subsystem to dynamically adjust the computational load of the analysis.

摘要： A system and method for ascertaining the identity of an object within an enclosed article. The system includes an acquisition subsystem utilizing a stationary radiation source and detector, a reconstruction subsystem, a computer-aided detection (CAD) subsystem, and a 2D/3D visualization subsystem. The detector may be an energy discriminating detector. The acquisition subsystem communicates view data to the reconstruction subsystem, which reconstructs it into image data and communicates it to the CAD subsystem. The CAD subsystem analyzes the image data to ascertain whether it contains any area of interest. Any such area of interest data is sent to the reconstruction subsystem for further reconstruction, using more rigorous algorithms and further analyzed by the CAD subsystem. Other information, such as risk variables or trace chemical detection information may be communicated to the CAD subsystem to be included in its analysis.

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.

摘要： An imaging technique is provided for acquiring scatter free images of an object. The technique includes acquiring a plurality of projection images of the object using a source and a detector oriented at a plurality of projection angles relative to the object, and generating a plurality of scatter free projection images by correcting the plurality of projection images based on respective ones of a plurality of stored scatter images. The scatter images are generated and stored for each of the projection angles by positioning a scatter rejection plate between the object and the detector. The technique further includes reconstructing a three-dimensional image of the object based on the scatter free projection images.

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.
