A computer-implemented method of automated X-ray inspection during the production of printed circuit board, PCB, assemblies. The method includes capturing an X-ray image of a PCB assembly, determining a first error indicator based on image processing of the captured X-ray image, determining, in case the first error indicator indicates the PCB assembly as faulty, a second error indicator based on the captured X-ray image using a trained adaptive algorithm, and outputting the second error indicator as a result of the inspection.

Described is an anti-vibration fixture comprising a radiolucent enclosure and a vibration-dampening material attached to an inside face of the radiolucent enclosure. The vibration-dampening material is configured to receive a component for nondestructive testing by computed tomography (CT) scanning. The anti-vibration fixture further comprises a plurality of fasteners attached to opposing faces of the radiolucent enclosure.

An integrated microtomography and optical imaging system includes a rotating table that supports an imaging object, an optical stage, and separate optical and microtomography imaging systems. The table rotates the imaging object about a vertical axis running therethrough to a plurality of different rotational positions during a combined microtomography and optical imaging process. The optical stage can be a trans-illumination, epi-illumination or bioluminescent stage. The optical imaging system includes a camera positioned vertically above the imaging object. The microtomography system includes an x-ray source positioned horizontally with respect to the imaging object. Optical and x-ray images are both obtained while the imaging object remains in place on the rotating table. The stage and table are included within an imaging chamber, and all components are included within a portable cabinet. Multiple imaging objects can be imaged simultaneously, and side mirrors can provide side views of the object to the overhead camera.

The invention discloses a scanning method and apparatus suitable for scanning a pipeline or process vessel in which a beam of gamma radiation from a source is emitted through the vessel to be detected by an array of detectors which are each collimated to detect radiation over a narrow angle relative to the width of the emitted radiation beam.

An X-ray imaging system (XI) configured for phase contrast and/or dark-field imaging The system comprises an X-ray source (XS) operable to cause X-radiation to emanate from a focal spot (SF) of the source (XS) and an X-ray sensitive detector (D) operable to SMF detect the X-radiation after interaction of said X-radiation with an object to be imaged, if present, between the X-ray source and the detector (D). A control logic (CL) is operable to cause the X-ray imaging apparatus to operate in any one of two modes, an object image acquisition mode and a scattering measurement mode. When in scattering measurement mode, the X-radiation receivable at the detector comprises a higher proportion of scattering radiation than in X-radiation receivable when the system is in object image acquisition mode.

A method for identifying a foil position in a power storage device includes: analyzing the power storage device by X-ray CT analysis to obtain an X-ray absorbed amount at each position; acquiring an on-path X-ray absorbed amount at each on-path position on a specific imaginary line passing through an electrode sheet; and identifying a foil position of an electrode foil through which the specific imaginary line passes, based on the on-path X-ray absorbed amount. The foil position identifying includes fitting to determine an approximate curve that changes to fit a change in the on-path X-ray absorbed amount in a fitting region and generates a single peak in the fitting region, and estimating a foil position of a single electrode foil from the on-path position corresponding to the single peak of the determined approximate curve.

An x-ray inspection apparatus may comprise an x-ray source, an x-ray detector, and a drive assembly. The drive assembly may be configured to lift a part carrier such that the part carrier is disengaged from a feed assembly and an object mounted on the part carrier is positioned between the x-ray source and the x-ray detector. The feed assembly may be configured to feed part carriers into and out of the x-ray inspection apparatus. The drive assembly may be further configured to subsequently lower the part carrier such that the part carrier is reengaged with the feed assembly.

Systems and methods are provided for improved intra-operative micro-CT imaging of explanted tissue samples and for improved visualization of such samples. These embodiments provide for reduced scan times and the ability for radiologists to quickly receive useful scan imagery and to provide accurately-communicated recommendations to the operating surgeon. Improved scan visualization methods facilitate surgeon and radiologist interaction with the scan data, including of annotation, viewing, and reorientation to accurately reflect the orientation of imaged tissue samples relative to the body prior to explantation. Improved visualization methods include color-coded sample texturing to indicate sample orientation, color-coded tumor visualization to indicate proximity to sample margins, and intuitive methods for adjusting the location and orientation of two-dimensional visualizations relative to the sample.

A rock modeling method is disclosed. An effective rock property of a rock sample is determined based on a digital rock. Instead of upscaling rock properties, the digital rock is constructed by upscaling relationships and rock physics models of segmented rock materials. Relationships between different scalar, elastic, and petrophysical properties of different segmented rock materials are established at the high-resolution scale where the pore structure is resolved. These relationships are then applied to the same rock material at the macro-scale. Finally, the effective rock properties are computed using Darcy-like solver to get the final values at a representative rock volume. Embodiments allow for performing non-destructive fluid/solid substitution and other reproducible digital experiments to study control factors that affect these relationships within rocks. Accordingly, for unconventional reservoirs, organic matter porosity can be filled with organic matter (kerogen) to build a rock physics model based on kerogen maturity and pore size.

The present embodiments generally relate to methods of non-destructively imaging plant root damage by insect root herbivores and evaluating the efficacy of insecticidal materials associated with the roots of plants against the insect root herbivores, useful for automated high throughput bioassays.
