摘要： An imaging method positions a heterogeneous object within a fixture having a chamber. The fixture also has a valve for receiving a gas and normally sealing the chamber. Thus, the object is within the chamber. Next the method positions the fixture within an active region of a CT machine, fluidly connects a gas line to the valve, and injects an inert gas into the chamber through the gas line and the valve. The inert gas may include one or more of the xenon, argon, and krypton. The method then increases the pressure within the sealed chamber to increase the density of the gas within the chamber, and directs x-ray energy toward the active region of the CT machine to produce a plurality of two-dimensional images of the object and the pressurized gas. Finally, the method generates a three-dimensional representation of the object from the plurality of images.

摘要： A method and apparatus for assessing a threat status of a piece of luggage. The method comprises the steps of scanning the piece of luggage with penetrating radiation to generate image data and processing the image data with a computing device to identify one or more objects represented by the image data. The method also includes further processing the image data to compensate the image data for interaction between the object and the penetrating radiation to produce compensated image data and then determine the threat status of the piece of luggage.

摘要： Plural of virtual curved surface solids, each of which is a curved surface solid formed by a combination of plural of virtual spheres, is placed so as to fill in space voxels, referring to porous-body data in which positional information is associated with voxel-type information (step S100). Information regarding a flow rate for each space voxel when a fluid passes through a porous body is derived by executing a fluid analysis based on the porous-body data (step S110). A flow-rate-weighted mean diameter Ru, which is a weighted average obtained by weighting an equivalent diameter R′i for each virtual curved surface solid with a volume Vi and an average flow rate Ui for each virtual curved surface solid, is derived based an information regarding the virtual curved surface solids and information regarding the flow rate for each space voxel (step S120).

摘要： A correlative evaluation of a sample (104) using a combined x-ray computed tomography (CT) and x-ray fluorescence (XRF) system and the method for analyzing a sample (104) using x-ray CT and XRF is disclosed. The CT/XRF system (10) includes an x-ray CT subsystem (100) for acquisition of volume information and a confocal XRF subsystem (102) for characterization of elemental composition information. Geometrical calibration is carried out between the XRF subsystem (102) and the X-ray CT subsystem (100) such that a region of interest defined during X-ray CT acquisition can be retrieved by the XRF subsystem (102) for a subsequent XRF acquisition. The system (10) combines the sub-micrometer spatial resolution 3-D imaging capability of x-ray CT with the elemental composition analysis of confocal XRF to provide 3-D elemental composition analysis of a sample (104) with ppm level sensitivity. This is applicable to many scientific research and industrial applications, a prime example of which is the elemental identification of precious metal grains in crushed and ground ores and floatation tailings in the mining industry.

摘要： A multi energy, such as dual-energy (“DE”), x-ray imaging system data acquisition and image reconstruction system and method enables optimizing the image contrast of a sample. Using the DE x-ray imaging system and its associated user interface applications, an operator performs a low energy (“LE”) and high energy (“HE”) x-ray scan of the same volume of interest of the sample. The system creates a low-energy reconstructed tomographic volume data set from the set of low-energy projections and a high-energy tomographic volume data set from the set of high-energy projections. This enables the operator to control the image contrast of selected slices, and apply the information associated with optimizing the contrast of the selected slice to all slices in the low-energy and high-energy tomographic data sets. This creates a combined volume data set from the LE and HE volume data sets with optimized image contrast throughout.

摘要： The present invention pertains to a system and method for X-ray imaging wherein a targeted fluence at the detector for projection images can be achieved at a plurality of projection angles around the imaging subject by control of exposure times implemented during image acquisition. Exposure time for a second projection image may be determined by the fluence in a first projection image, and in a third projection image by the fluence in a second projection image, where projection images are acquired within two degrees of one another. An acquisition parameter calculation can be configured to calculate acquisition parameters, such as said exposure times, to achieve the targeted fluence in projection images and can be coupled to a rotation controller that implements the acquisition parameters by controlling a relative angle between the imaging subject and X-ray image acquisition device.
