The present disclosure provide pipe scanning systems suitable for performing integrity and reliability inspection of pipelines, including insulated and non-insulated pipelines. The pipe scanning system may include a track disposed about a surface of the pipeline (e.g., on top of the insulation for insulated pipelines or on top of the pipe for non-insulated pipelines) and a scanning device mounted on the track via a drive carriage. The drive carriage includes components to facilitate movement of the drive carriage and the scanning device along the track such that the scanning device travels about the circumference of the pipeline. The scanning device includes an x-ray emitter and a digital x-ray detector that may capture media content indicative of a scanned section of the pipeline (e.g., a 360° circumferential scan), and the media content may be analyzed to detect the presence of one or more defects, such as corrosion under insulation (CUI).

An insulated electrical component of an insulated electrical machine includes a conducting element, a first radiographically-visible conductor sensor node coupled to the conducting element, at least one second radiographically-visible conductor sensor node coupled to the conducting element a first distance in a predetermined direction from the first radiographically-visible conductor sensor node, and an insulating material bonded to the conducting element. In some embodiments, the insulated electrical component further includes a first radiographically-visible insulator sensor node coupled to the insulating material and not coupled to the conducting element and at least one second radiographically-visible insulator sensor node coupled to the insulating material and not coupled to the conducting element a second distance from the first radiographically-visible insulator sensor node. The radiographically-visible sensor nodes are distinguishable from the conducting element and the insulating material in a radiographic image. Methods of manufacturing and non-destructive testing of insulated electrical components are also disclosed.

A radiation imaging apparatus comprises a readout unit and a gain map generation unit. The readout unit repetitively outputs the image data a plurality of times during a period in which radiation irradiation is performed for generating the gain map data. The gain map generation unit collects a plurality of image data output from the readout unit, and in response to stop of the radiation irradiation, generates the gain map data based on the plurality of image data except at least finally collected image data in the plurality of collected image data.

An x-ray imaging apparatus includes an x-ray source module configured to output source x-rays, a pencil-beam-forming module having input and output ports, and a module engagement interface that enables a user to select aligned and non-aligned configurations of the source and pencil-beam-forming modules. In the aligned configuration, the pencil-beam-forming module is aligned with the source module to receive source x-rays at the input port and to output a scanning pencil beam through the output port toward a target. In the non-aligned configuration, the pencil-beam-forming module is not aligned with the x-ray source module to receive the source x-rays nor to output the pencil beam, but instead enables the source x-rays to form a stationary, wide-area beam directed toward the target. Example embodiments can be handheld, can enable both backscatter imaging and high-resolution transmission imaging using the same apparatus, and can be employed in finding and disarming explosive devices.

A fluid pressure loading device applied to an industrial computed tomography scanning test system includes a body, a sample accommodating chamber and at least one fluid medium chamber being provided in the body.
