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： 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： 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.
