摘要： The present specification relates to a method for enabling an operator to perform visual layer separation, the method including: retrieving at least one X-ray scan image from a memory in data communication with an inspection system, wherein the image comprises a first area of pixels representative of a target object obscured by a clutter object and a second area of pixels representative of the clutter object; receiving a selection of the pixels representative of the first area; receiving a selection of the pixels representative of the second area; determining if the selected second area meets a predefined quality threshold; if the selected second area meets the predefined quality threshold, generating a modified at least one X-ray image; and if the selected second area does not meet the predefined quality threshold, prompting the operator to select a different second area of pixels representative of the clutter object.

摘要： Systems and methods are used to increase the penetration and reduce the exclusion zone of radiographic systems. An X-ray detection method irradiates an object with X-ray fanlets including vertically moving fan beams, each fanlet having an angular range smaller than the angular coverage of the object. The fanlets are produced by modulating an X-ray beam, synchronizing the X-ray beam and the fanlets, detecting the fanlets irradiating the object, collecting image slices from the detector array corresponding to a complete scan cycle of the fanlets, and processing the image slices collected for combining into a composite image.
