Some embodiments include a radiographic inspection system, comprising: a drive mechanism configured to move along a structure; a detector attached to the drive mechanism; a radiation source attached to the drive mechanism and positionable relative to the detector such that a width of the structure casts a radiation shadow on an active area of the detector; and control logic coupled to the detector and configured to: receive an image from the detector; generate side wall loss information based on the image; and generate bottom wall loss information based on the image.

A defect inspection system includes an X-ray generator that generates X-ray to be irradiated to a structure, and an X-ray detector that detects the X-ray generated by the X-ray generator and transmitted through the structure. In particular, the X-ray generator is configured to be moved by a first transporting means, and the X-ray detector is configured to be moved by a second transporting means. The system further includes a control unit configured to control and operate the first transporting means and the second transporting means.

Scanning systems may include a stator, a rotor supporting at least one radiation source and at least one radiation detector rotatable with the rotor, and a motivator operatively connected to the rotor. The stator, the rotor, the at least one radiation source, and the at least one radiation detector may be located within a housing. A conveyor system may extend through the housing and the rotor. A shielding system including a series of independently movable energy shields sized, shaped, and positioned to at least partially occlude a pathway along which the conveyor system extends may extend from an entrance to the housing, through the rotor, to an exit from the housing. A control system may be configured to cause the shielding system to automatically and dynamically move individual energy shields in response to advancement of one or more objects supported on the conveyor system.

The present disclosure provides a radiation inspection apparatus and a radiation inspection method. The radiation inspection apparatus includes: a radiation inspection device comprising a ray source and a detector that cooperates with the ray source to perform scanning inspection on an object to be inspected, the radiation inspection device having an inspection channel for the object to be inspected to pass through when scanning inspection is performed thereon; and traveling wheels provided at the bottom of the radiation inspection device to enable the radiation inspection apparatus to travel in an extension direction of the inspection channel, and the traveling wheels are configured to rotate 90° to enable the radiation inspection apparatus to travel in a direction perpendicular to the extension direction of the inspection channel.

A virtual 511 KeV attenuation map is generated from CT data. Spectral or multiple energy CT is used to more accurately extrapolate the 511 KeV attenuation map. Since spectral or multiple energy CT may allow for material decomposition and/or due to additional information in the form of measurements at different energies, the modeling used to generate the 511 KeV attenuation map may better account for all materials including high density material. The extrapolated 511 KeV attenuation map may more likely represent actual attenuation at 511 KeV without requiring extra scanning using a 511 KeV source external to the patient. The virtual 511 KeV attenuation map (e.g., CT data at 511 KeV) may provide more accurate PET image reconstruction.

A device to inspect a pipeline includes a device housing movable relative to the pipeline, a radiation device, and an imaging device. The radiation device is coupled to the device housing and disposed adjacent to the pipeline. The imaging device is coupled to the device housing and disposed adjacent to the pipeline. The imaging device is disposed opposite to the radiation device relative to the pipeline. The imaging device receives radiation from the radiation device to provide an imaging signal. Because the radiation device and the imaging device are disposed opposite to each other relative to the pipeline, the pipeline inspection device can provide an enhanced image in a single pass of the pipeline.

In a nondestructive inspection of a defect of a welded portion of a pipe or a pipe member, work efficiency of a radiation transmission test is improved by reducing a burden on a worker, and an inspection accuracy is improved. Imaging data is acquired by transmitting radiation through a welded portion of the pipe to be inspected. Processing of associating determination data indicating a result of determining a defect of the welded portion of the pipe to be inspected based on a distribution of a transmission intensity of the radiation obtained from the imaging data with image data showing the distribution of the transmission intensity of the radiation is performed. As a result, through use of the imaging data, image data and determination data associated with the image data can be obtained, and the burden on the worker can be reduced.

A method of inspecting a separation vessel may utilize off axis gamma scanning. During scanning, a gamma radiation source can emit gamma radiation through a separation vessel toward a detector, and the detector can detect radiation emitted by the gamma radiation source and passing through the separation vessel. The gamma radiation source may be positioned at a first vertical elevation along the separation vessel and the detector positioned at a second vertical elevation along the separation vessel different than the first vertical elevation. As a result, a radiation path may be defined between the gamma radiation source and the detector that transects the separation vessel at a non-zero degree angle with respect to a horizontal plane.

The radiation inspection apparatus includes: a radiation inspection device comprising a ray source and a detector that cooperates with the ray source to perform scanning inspection on an object to be inspected, the radiation inspection device having an inspection channel for the object to be inspected to pass through when scanning inspection is performed thereon; and traveling wheels provided at the bottom of the radiation inspection device to enable the radiation inspection apparatus to travel in an extension direction of the inspection channel, and the traveling wheels are configured to rotate 90° to enable the radiation inspection apparatus to travel in a direction perpendicular to the extension direction of the inspection channel.

A non-destructive inspection system includes: a neutron emission unit 12 capable of emitting neutrons pulsed; a neutron detector capable of detecting the neutrons emitted from the neutron emission unit and penetrating through an inspection object; a storage unit storing attenuation information indicating a relationship between a material of the inspection object and attenuation of the neutrons; and a calculation unit capable of calculating distance information indicating a position of a specific portion in the inspection object in accordance with time change information which is information on a change over time in an amount of the neutrons detected by the neutron detector. The calculation unit is capable of generating information related to an amount of the specific portion from information based on the amount of the neutrons according to the time change information, using the distance information and the attenuation information.
