Provided is a tube weld X-ray inspection device for inspecting an abnormality, such as a tube welding part crack, of a heat exchanger by using X-rays.

Disclosed herein is an image sensor comprising: a first package comprising a plurality of radiation detectors mounted on a printed circuit board (PCB); wherein a dead zone of the first package does not extend between neighboring radiation detectors among the plurality of radiation detectors; wherein the radiation detectors have no guard rings or sidewall doping.

An X-ray inspection system is presented. The X-ray inspection system comprises an X-ray source, an X-ray scintillator, a light detector, a first objective lens, and a second objective lens. The first objective lens is positioned between the X-ray scintillator and the light detector. The second objective lens is positioned between the first objective lens and the light detector.

An inspection position identification method that allows accurate inspection to be performed without in-advance identification of the position of an inspection plane in an inspected target. A three-dimensional image generation method that allows generation of a three-dimensional image for inspection without in-advance identification of the position of an inspection plane in an inspected target and then allows inspection to be performed. An inspection device including the methods. An inspection device includes a storage unit, which stores a radiation transmission image of an inspected object and a three-dimensional image generated from the radiation transmission image, and a control unit. The process carried out by the control unit for identifying an inspection position in a three-dimensional image includes identifying the position of a transmission picture of the inspection position in the radiation transmission image and identifying the inspection position in the three-dimensional image from the position of the transmission picture.

Aspects of the present disclosure relate to the fabrication and use of a curved X-ray detector panel, suitable for use in imaging pipes or other curved objects to which the curved detector may be fitted. In certain embodiments, the curved detector panel is fabricated using a thin, flexible substrate that is unbreakable or resistant to breaking.

Provided is a tube weld X-ray inspection device for inspecting an abnormality, such as a tube welding part crack, of a heat exchanger by using X-rays.

A frame assembly for inspection of pipeline girth weld, having a support frame releasably coupled to a mounting band that comprises of two clamshell halves. The clamshell halves are coupled via quick release coupling mechanisms. By removing one of the clamshells, or uncouple the two clamshells at one coupling point, the frame assembly permits a RTR scanner assembly to be laterally displaced along the length of the pipeline.

An X-ray inspection system is presented. The X-ray inspection system comprises an X-ray source, an X-ray scintillator, a light detector, a first objective lens, and a second objective lens. The first objective lens is positioned between the X-ray scintillator and the light detector. The second objective lens is positioned between the first objective lens and the light detector.

A flexible DR detector assembly bendable along one axis and not bendable along a second axis is used with an x-ray source for radiographic imaging of a human anatomy, veterinary anatomy, or industrial equipment.

A method includes determining a predicted contrast-to-noise ratio sensitivity function (CNR SF) for crack detection of a predetermined target flaw size with the radiographic inspection system in the selected set-up. The method also includes qualifying an inspection image quality indicator (IQI) for the predetermined target flaw size for use in the radiographic inspection system in the selected set-up. The method also includes performing an inspection process. The inspection process includes selecting the qualified inspection IQI for the predetermined target flaw size. The inspection process also includes performing an inspection test on the qualified inspection IQI using the radiographic inspection system in the selected set-up. The inspection process also includes determining one or more inspection output parameters. The inspection process also includes verifying that the one or more inspection output parameters meet or exceed minimum qualified values to qualify the radiographic inspection system in the selected set-up.
