  • Patent number: 11307153
    Abstract: In order to increase reproducibility of a reconstructed tomographic image without increasing the computational load, detection is performed by oversampling in (N+n) directions during imaging for detection by N detection elements. A vector having N×(N+n) elements is obtained, and vector decimation step is performed in which a total of n×N elements corresponding to a sequence {k} 30 denoting a decimation order are removed. In a discrete Radon transform step, a corresponding discrete Radon inverse matrix WSQ?140 is operated, and in an image data generation step, de-vectoring is performed, thereby tomographic image data are acquired. When oversampling is used, a discrete Radon inverse matrix WSQ?1 is obtained. Therefore, a tomographic image is obtained by matrix computation without resorting to iterative approximation.

  • Patent number: 11275039
    Abstract: A two-dimensional X-ray diffractometer uses an X-ray source that emits a divergent beam toward a sample under test. The divergent beam has a substantially fixed width in a first direction perpendicular to its propagation direction, and a thickness in a second direction perpendicular to the propagation direction that increases proportionally to a distance from the source. An aperture may be used to block a portion of the beam in the second direction, and the sample is positioned so that the beam illuminates a two-dimensional area of the sample surface. The detector detects an X-ray signal diffracted from the sample across a two-dimensional detection area, and may use a one-dimensional detector array that collects diffracted X-ray signal at a number of different positions. The source, detector and sample may be mounted to a goniometer to maintain them in a desired relative orientation.
