摘要： Material loss may be estimated from 2D digital radiographs using double wall single imaging (DWSI) technique using a system for estimation of material loss from 2D digital radiographs comprising one or more calibration samples, each with one or more known defects; one or more radiofrequency emissions sources; one or more radiofrequency emissions detectors; one or more radiofrequency emissions processors operatively in communication with at least one radiofrequency emissions detector; and software which is used to process a background image representative of a background proximate a structure which is obtained and radiofrequency emissions emitted the structure at a predetermined location. The radiofrequency emissions detector detects radiofrequency emissions reflected from the structure and the radiofrequency emissions processor used to further process the radiofrequency emissions by creating a two-dimensional image of the detected radiofrequency emissions from which the background image is subtracted using median filtering.

摘要： A method and system for scanning an elongate structure. A scanner in a scanning system is moved axially along the elongate structure using a translating structure in the scanning system. The elongate member is scanned axially as the scanner moves axially along the elongate structure. The scanner is moved rotationally around the elongate structure at a location in which an inconsistency is detected at the location during an axial scan. The elongate structure is scanned rotationally at the location while the scanner moves rotationally around the elongate structure.

摘要： The type and/or properties of a substance is identified highly accurately regardless of the thickness of the substance. A data processing apparatus processes counts detected at each of pixels of a photo counting detector in each of a plurality of energy ranges of X-rays. The X-rays are radiated from an X-ray tube, and transmitted through an object. The apparatus calculates an image of the object based on the counts, and sets a region of interest on the image. The apparatus further removes, from the pixel, pixel information showing a background present in the region of interest, and calculates, pixel by pixel, inherent information inherent to the substance, based on the counts detected at each of the respective pixels in each of the energy ranges of the X-rays in the region of interest. The inherent information indicates a transmission characteristic inherent to the X-rays.

摘要： Detection can be performed even for a thick inspection target object through time delay integration without degradation of spatial resolution. There is provided an X-ray inspection device configured to include: an X-ray source that generates X-rays; a transport unit that performs transporting a sample; a detecting unit that has a time delay integration type detector which detects X-rays generated by the X-ray source and transmitted through the sample transported by the transport unit; and a defect determining unit that processes a signal obtained by detecting the X-rays transmitted through the sample by the time delay integration type detector of the detecting unit and determines a defect in the sample. The transport unit performs transporting the sample while causing the sample to rotate in synchronization with the transporting when the sample passes in front of the time delay integration type detector of the detecting unit.

摘要： An inspection method include introducing a mixture of expanding foam and a particulate material into a region of interest of an object, fixing the powder within the region of the interest relative to the object, and acquiring image data of the object and particulate mixture using an x-ray source and an x-ray detector. The particulate has a density that is greater than the density of a material forming the object to provide contrast between the region of interest and the object in an image generated using the image data.

摘要： A radiation image obtained by imaging a test object irradiated with radiation is acquired. A standard image which is a normal radiation image of the test object imaged under the same imaging condition as in the acquired radiation image is stored in a standard image storage unit. Differential values of pixel values between corresponding pixels of the radiation image acquired by the radiation image acquisition unit and the standard image stored in the standard image storage unit are detected. A differential region between the radiation image and the standard image so that positive and negative of the differential values in the differential region can be determined on the basis of a detection result of the differential value detection unit is displayed on a display unit.

摘要： A scanning method which is a method of identifying a change in the density of an object includes arranging a source of ionizing radiation and an array of radiation detectors Dn, where n is an integer from 1 to N, capable of detecting the radiation in such a way that radiation counts are counted by the detectors as the source and detectors are rotated around the object and normalized counts values are collated in a matrix such that a pattern may be detected within the matrix from which the presence of a change in the density of the object at a location lying on at least one of the radiation paths may be inferred.

摘要： An X-ray inspecting apparatus, with which X-rays of a broad energy band can be detected while manufacturing costs are suppressed, comprises an X-ray radiation device, a line sensor assembly, and other components. The line sensor assembly has a plurality of detection units and other components. Each detection unit has a scintillator, a detection main body including a plurality of elements disposed thereon, and a ceramic substrate supporting the scintillator and detection main body. In the line sensor assembly, the plurality of detection units etc. are aligned in a forward-backward direction so that the scintillators and the detection main bodies of the detection units etc. are aligned without gaps with the scintillators and detection main bodies of adjacent detection units.

摘要： This invention utilizes two sensing technologies in combination with or in isolation of an automated inspection vehicle to conduct inspections of internal rail flaws in steel railroad track. A vehicle equipped with X-radiation sensing is used as a secondary method to assess the deviations in magnetic fields that are sensed by a primary sensor consisting of a single or multiple magnetometers. The magnetometers sense changes in magnetic field that are correlated to the flaws inside the steel rail. The combination of technologies improves the probability to detect railroad flaws and offers the ability to accurately track and monitor flaws.

摘要： A device and method for the radioscopic examination of a continuous strip-shaped material of rubber which runs continuously in particular. During the movement, the strip-shaped material is x-rayed by a radioscopic measurer and the entire cross-sectional surface is detected so that foreign bodies or defects present in the material are detected according to their position and orientation. An elimination device removes the previously identified foreign body during the feed movement of the material in that a tool, configured as a punching tool, of the elimination device is moved synchronously with the material.
