摘要： [Problem to be solved] A radiographic phase-contrast imaging apparatus includes two gratings including the first grating and the second grating, which are positioned parallel to each other at a predetermined interval, and obtains a radiographic phase-contrast image using these gratings, wherein a plurality of fringe images used to obtain a radiographic phase-contrast image are obtained by a single imaging operation.
[Solution] The first and second gratings are adapted to form a moire pattern when a periodic pattern image formed by the first grating is superimposed on the second grating. Based on an image signal of the moire pattern detected by the radiographic image detector, image signals of the fringe images, which correspond to different pixel groups located at different positions from one another with respect to a predetermined direction, are obtained by obtaining image signals read out from pixels of each pixel group, which includes pixels arranged at intervals of a predetermined number of pixels in the predetermined direction, as the image signal of each fringe image, where the predetermined direction is a direction parallel to or a direction intersecting a period direction of the moire pattern other than a direction orthogonal to the period direction of the moire pattern. Then, a phase-contrast image is generated based on the obtained image signals of the fringe images.

摘要： A method of determining the proportions of different powders (26, 28, 30) in a powder comprises obtaining a sample of a powder (24), adding and mixing the sample into a molten material (22) and freezing the mixture of powder (24) and molten material (22) to form a block (20). Computed tomography (12) is performed on the block (20) to produce a three-dimensional image of the block (20), the three-dimensional image of the block (20) comprises a first shade, a second and a third shade corresponding to the material (22), a first powder particle (26) and a second powder particle (28, 30). The three-dimensional image of the block (20) is analysed to count the number of regions exhibiting the second shade and the third shade corresponding to the number of first powder particles (26) and second powder particles (28, 30) respectively. The fraction of second particles (28, 30) in the powder is determined by dividing the number of second powder particles (28,30) by the sum of the number of first powder particles (26) and the number of second powder particles (28, 30).

摘要： A method for determining effects of perforation on a rock formation includes obtaining a sample (110) of the rock formation. A perforation tunnel (112) is created in the sample of the rock formation. The core sample (110) is either subdivided into subsamples and a three dimensional tomographic image is made of each subsample and/or a three dimensional tomographic image is made of the sample of rock formation and the image thereof is segmented into sub images of selected subvolumes of the rock formation sample. At least one physical property of the rock formation is estimated from each tomographic image.

摘要： An imaging system combines CT and XRD measurements, both measuring the XRD diffraction and the absorption as a function of energy. A goniometer 2, source 4 and two dimensional detector 10 may be used. Embodiments use relatively soft X-rays in the 5-25 keV range. An integrated mounting unit to mount the sample 8 close to detector 10 is also described.
