The present disclosure relates to X-ray imaging systems and methods. An exemplary system may comprise a distributed X-ray source arrangement, a fixed grating module, an X-ray detecting device, and a computer workstation. In one illustrative implementation, X-ray sources of the distributed incoherent X-ray source arrangement may sequentially generate and emit X-rays to an object to be detected. Further, for each exposure, the X-ray detecting device may receive the X-rays, wherein after a series of stepping exposures and corresponding data acquisitions, at each pixel of the X-ray detecting device, X-ray intensities are represented as an intensity curve; the intensity curve may be compared to an intensity curve in the absence of the object to be detected, and a pixel value at each pixel may be obtained from a variation of the intensity curves; and image information of the object to be detected may be obtained according to such pixel values.

A method for inspecting a vehicle includes acquiring a unique identity number of an insepected vehicle, carrying out X-ray scanning on the inspected vehicle to acquire an X-ray image of the inspected vehicle, retrieving at least one historical inspected image related to the unique identity number from a historical inspection database, determining, based on one template image selection algorithm selected from multiple template image selection algorithms, one of the at least one historical inspected images as a template image, determining a difference region between the X-ray image and the template image, and presenting the difference region to a user.

In an approach to X-ray inspection image display systems, a colorized X-ray inspection image is received comprising a monochrome X-ray inspection image that is colorized in accordance with an X-ray inspection system false colorization scheme. The colorized X-ray inspection image is filtered by performing pixel shading on the colorized X-ray inspection image to generate a custom colorized X-ray inspection image having a custom false colorization scheme that is different from the X-ray inspection system false colorization scheme.

Methodologies, systems, apparatus, and non-transitory computer-readable media are described herein to facilitate acquisition of volumetric data and volumetric image reconstruction. An imaging system can be configured to transport an object at a speed relative to the scan path of an X-ray source such that insufficient measurement data is collected for classically complete geometrical coverage. Iterative image reconstruction techniques may be used to generate volumetric images based on measured volumetric data of at least a portion of the object.

A method comprises: using a Scanning Electron Microscope (SEM) to acquire an image of a specimen; identifying one or more objects of interest within the SEM image; generating a scan mask indicating a first set of one or more regions corresponding to the identified one or more objects of interest; and based on the scan mask, providing instructions to the SEM to acquire one or more Electron Backscatter Diffraction (EBSD) images from the first set of one or more regions of the specimen, wherein the method is performed by at least one device including a hardware processor.

A terminal can include a display and a processor configured to generate a reconstructed image based on a plurality of X-ray images of a battery, and rotate the reconstructed image by a predetermined angle to generate a tilting image. Also, the processor can generate an electrode detection image based on the tilting image, the electrode detection image including a positive electrode of the battery and a negative electrode of the battery in which the positive electrode and the negative electrode are separated from each other, and detect whether the battery is defective based on the electrode detection image.

A method for masking a container in a computerized tomography (CT) image includes receiving a specimen secured in a container on a rotatable support surface and identifying the container. A mask corresponding to the container is determined. The specimen and container are rotated through a plurality of imaging angles. During rotation the specimen and container are imaged to obtain a set of 2D images and a 3D representation of the specimen and of the container are generated. A mask is applied to mask the 3D representation of the container. The resulting the 3D representation of the specimen is displayed.

A system and method for foreign object detection in meat processing is provided. The system and method combine microfocus X-ray tubes with dual energy X-rays to detect foreign objects in meat products. A dual energy image processing algorithm analyzes the dual energy X-rays passed through the meat product to identify the foreign object present therein. An alarm or other notification is then generated in response to the detection of a foreign object.

Ultralow-dose, x-ray or gamma-ray imaging is based on fast, electronic control of the output of a laser-Compton x-ray or gamma-ray source (LCXS or LCGS). X-ray or gamma-ray shadowgraphs are constructed one (or a few) pixel(s) at a time by monitoring the LCXS or LCGS beam energy required at each pixel of the object to achieve a threshold level of detectability at the detector. An example provides that once the threshold for detection is reached, an electronic or optical signal is sent to the LCXS/LCGS that enables a fast optical switch that diverts, either in space or time the laser pulses used to create Compton photons. In this way, one prevents the object from being exposed to any further Compton x-rays or gamma-rays until either the laser-Compton beam or the object are moved so that a new pixel location may be illumination.
