摘要： A method and apparatus is provided for detection of a particular material in an object, in particular in an item of luggage, by means of electromagnetic radiation in which the intensities of non-absorbed radiation from at least three radiation planes are measured and evaluated in associated detector apparatus, wherein an image is produced, initially from the intensities of the non-absorbed radiation, and then if single regions of low complexity are found which are characterized by approximately constant intensities, an estimation of the attenuation coefficient s performed and a material detection is carried out in the region according to an algorithm which calculates a three-dimensional reconstruction from different views.

摘要： A method of analyzing a target item utilizing multiple scanners is disclosed. The method can include providing an item comprising a material. The method can further include acquiring a first set of scan data associated with the item using a first scanner, and acquiring a second set of scan data associated with the item using a second scanner. The method can further include generating a first set of transform data from the first set of scan data, analyzing the first set of transform data to identify a subset of the first set of transform data associated with a first region, and analyzing the second set of scan data to identify a subset of the second set of scan data associated with a second region. The method can also include generating a measure that at least a portion of scan data is consistent with a presence of a candidate material in the item, where the portion of scan data is selected from at least one of the set consisting of: the subset of the first set of transform data and the subset of the second set of scan data.

摘要： An imaging system comprises a transmitter (24, 25), a receiver (24, 25, 21), and a controller (20) for directing the transmitter and the receiver to scan an object in a volume. The controller determines which sub-volumes of the volume the object is located within and then performs a fine scan in those sub-volumes. This reduces overall scanning time. The controller (20) may compare a received signal sample magnitude from the initial scan with a threshold to make the decision. The initial scan may be performed with a spot size to include only one or more particular volume elements within at least some of the sub-volumes.

摘要： Systems and methods for modeling are provided. The method can include acquiring scan data associated with a plurality of x-ray projections of an item. The method can further include determining at least one closed boundary curve associated with the item. For example, the method can determine a first maximum area based on the scan data and determine at least one edge of the first maximum area. The method can further generate a model of the item using the closed boundary curve and a first material specific parameter for a material within the closed boundary curve. The method can utilize the model to generate computed scan data, compare the computed scan data to the scan data, and determine a goodness of fit. The method can further adjust the model of the item by altering at least one of the closed boundary curve and the material specific parameter.
