  • Patent number: 10874364
    Abstract: An apparatus and method for three-dimensional inspection of an object by X-rays. The apparatus includes an X-ray generator and a digital imaging device spaced from each other by a distance which defines a magnification by 1 on the imaging device. The apparatus also includes a means for moving the X-ray generator and identically the imaging device by unitary movements in two orthogonal directions. Each unitary movement corresponds to an integer number fraction of the side of the imaging device, and obtains, by successive shots after each unitary movement, a matrix set of sub-images overlapping in the plane of extension of the imaging device. Each sub-image has a center with coordinates in a plane of magnification equal to N. An image processing means performs magnification of each sub-image and determines a stretch factor enabling the coincidence of the sub-images representing all or part of a predefined element of interest.
