    摘要： An x-ray imaging system (10), such as a X-ray computerised tomographic system, may acquire a series of radiographs at different detector positions along a first translation axis or a second translation axis parallel to orientation directions of detector pixels of a radiation detector (14). In a first embodiment, the different detector positions may be separated by a distance less than a linear size of the radiation detector (14) along the first translation axis or the second translation axis, respectively. The radiographs may be assembled into a radiograph larger than each radiograph in the series of radiographs, resulting in image stitching. In a second embodiment, the different detector positions may be separated by a distance less than a pixel size of the radiation detector (14), also referred as sub-pixel shifting of the detector. The radiographs may be assembled to form a radiograph with a higher resolution than the acquired radiographs, resulting in superresolution.

    摘要： Methods and systems for luggage visualization perform virtual unpacking by visually moving an object image away from its original pose. A scanned 3D volume is segmented guided by a confidence measure to create a label volume whose voxels specify the detected object IDs. The luggage dataset and the label volume are visualized by volume rendering. Using an automatic coloring algorithm, any pair of objects whose projections are adjacent in an image are assigned distinct hues. A layered framework efficiently renders a scene mixed with packed luggage, animated unpacking objects, and already unpacked objects put aside for further inspection. A GPU is used to automatically select objects that are not blocked by others and can be unpacked.

    摘要： The invention concerns a method and apparatus for scanning bodies, typically human bodies (12) for security or medical purposes. In the method, the body (12) is scanned with a beam (20) of X-radiation of sufficiently low intensity that no physiological damage is suffered. The X-radiation transmitted by the body (12) is then converted into an optical image. The optical image is intensified and converted into an electronic image. The electronic image is manipulated to produce a scanned image of the body or a portion of the body. The scanned image is typically a video image.

    摘要： A method (500), system and apparatus for processing a radiographic image of a scanned object is disclosed. A pixel offset correction is performed (510) 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 (520) to floating point format and the converted pixels are multiplied (530) by a gain factor. Optionally the resulting pixels are recursively averaged with previous results. The resulting pixels are converted (550) to integer format and the converted pixel values are clamped to a maximum value using saturation arithmetic Non-functional pixel correction (560) 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 (580) to enhance features of interest. The resulting pixel value is mapped (570) 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.
