Described herein are examples of interfaces for designing and/or configuring custom assisted defect recognition (ADR) systems and/or workflows. In some examples, the ADR systems and/or workflows may be designed and/or configured using visual tools, such as, for example, node based processing tools. In some examples, the ADR workflows may be used to analyze two dimensional (2D) and/or three dimensional (3D) image scans, such as might be generated by industrial X-ray scanning systems.

Interfaces for assisted defect recognition systems

Described herein are examples of industrial radiography systems that enable rotation of a part about a custom axis that is offset from an actual rotation axis of a rotatable fixture that retains the part. This may be valuable in situations where it is difficult, impractical, and/or impossible to align the center of the part with the center of the rotatable fixture. In some examples, the custom axis rotation may be implemented on existing radiography machines, without requiring physical alteration of the radiography machines, integration of new components into the radiography machines, and/or risk of instability to the part and/or radiography machines.

Customizable axes of rotation for industrial radiography systems

An example scan procedure generation system includes: a display; a processor; and a computer readable storage medium comprising computer readable instructions which, when executed, cause the processor to: output, via the display, a first visual representation of an arrangement of a radiation source, a radiation detector, a workpiece positioner, and a workpiece; and based on positions and orientations of the radiation source, the radiation detector, the workpiece positioner, and the workpiece, generate a scanning procedure for execution by a physical scanner having a physical radiation source, a physical radiation detector, and a physical workpiece positioner, wherein the generated scanning procedure comprises a plurality of movements of one or more of the physical radiation source, the physical radiation detector, and the physical workpiece positioner and a plurality of image captures to capture a plurality of scan images of a physical workpiece corresponding to the workpiece in the first virtual representation.

Scan procedure generation systems and methods to generate scan procedures

A system for non-destructive evaluation of an object uses a spherical coordinate system to control two robotic arms. In some examples, the system includes a radiation source coupled to one robotic arm, a radiation detector coupled to the other robotic arm; and a control unit configured to determine, based on input, a first position located on a first surface of a first sphere within the spherical coordinate system; determine, based on the input, a second position located on a second surface of a second sphere within the spherical coordinate system, wherein the second position is located opposite a midpoint of the spherical coordinate system from the first position; and control a motion of the source robotic arm and the detector robotic arm such that the radiation source and the radiation detector move to different ones of the first position and the second position.

Dual robot control systems for non-destructive evaluation

An example scanner positioning control system includes: a display; a processor; and a computer readable storage medium comprising computer readable instructions which, when executed, cause the processor to: output, via the display, a first visual representation of an arrangement of a radiation source, a radiation detector, and a workpiece positioner; identify a change to be made to the arrangement of at least one of the radiation source, the radiation detector, or the workpiece positioner; output, via the display, a second visual representation of the arrangement of the radiation source, the radiation detector, and the workpiece positioner based on the change to be made to the arrangement; and control a scanner positioning system to physically move the at least one of the radiation source, the radiation detector, and the workpiece positioner based on the change.

Systems and methods to control radiation scanner positioning

An imaging system generates a first radiograph based on a first pattern of radiation detected by a Linear Diode Array (LDA) radiation detector positioned to detect a radiation beam emitted by a radiation generator. The LDA radiation detector comprises a plurality of modules. Each respective module of the plurality of modules comprises a respective plurality of photodiodes corresponding to pixels. Furthermore, the imaging system may determine, based on the first radiograph, a size of a gap between two of the modules of the LDA radiation detector. After determining the size of the gap, the imaging system may generate a second radiograph based on a second pattern of radiation detected by the LDA radiation detector. The imaging system may generate a third radiograph by modifying, based on the size of the gap, the second radiograph to compensate for the gap.

Gap resolution for linear detector array

An x-ray imaging system may include an x-ray generator, one or more radiation detectors, a rotary stage, a linear translation stage, a motion control system, and a data acquisition system. The rotary stage has an axis of rotation arranged perpendicular to an axis of an x-ray beam emitted by the x-ray generator. The linear translation stage may be configured to move the rotary stage linearly along an axis aligned with the axis of rotation of the rotary stage. The motion control system may synchronize rotational motion of the rotary stage and linear motion of the linear translation stage. The data acquisition system may comprise processors configured to receive user input parameters. The processors may configure, based at least in part on the user input parameters, the x-ray imaging system to acquire radiographs. The processors may generate a three-dimensional image from the radiographs.

Helical computed tomography

An x-ray imaging system (), such as a X-ray computerized tomographic system, may acquire a series of radiographs at different detector positions along a first translation axis or a second translation axis parallel to orientation directions of detector pixels of a radiation detector (). In a first embodiment, the different detector positions may be separated by a distance less than a linear size of the radiation detector () along the first translation axis or the second translation axis, respectively. The radiographs may be assembled into a radiograph larger than each radiograph in the series of radiographs, resulting in image stitching. In a second embodiment, the different detector positions may be separated by a distance less than a pixel size of the radiation detector (), also referred as sub-pixel shifting of the detector. The radiographs may be assembled to form a radiograph with a higher resolution than the acquired radiographs, resulting in superresolution.
