Abstract: An X-ray CT examination installation, having an X-ray tube including a focus, that creates a fan beam or a conical beam which X-rays the whole of a detector at a fixed distance from the focus, and an examination carriage, for supporting an object to be examined, the carriage having an axis of rotation perpendicular to the fan beam, wherein the examination carriage can be fixed inside the fan beam close to an edge axis which meets the detector at the edge, and can be moved on a measuring line that centrally runs at an angle to a central axis which meets the detector. The invention also relates to a CT method of examining objects, in particular of various sizes, by means of an X-ray CT examination installation generally identified above.

Abstract: The invention relates to an X-ray CT examination installation, with an X-ray tube with a focus, which creates a fan beam or a conical beam which X-rays the whole of a detector located at a defined distance from the focus, and with an examination carriage, for receiving an object to be examined, which has an axis of rotation rotatable perpendicular to the plane of the fan beam or to the central axis of the conical beam. It is provided according to the invention that the examination carriage can be fixed on at least one measuring point, wherein each of these measuring points is arranged such that the axis of rotation is on a measuring line which emanates from the focus and includes a tilt angle ? with the central axis of the fan beam or the conical beam. The invention also relates to a CT method of examining objects, in particular of different sizes, by means of an X-ray CT examination installation according to the invention.

Abstract: The invention relates to a CT method for recording projection data of an object for examination in the field of non-medical applications by means of X-rays in which projection data for different angular positions of the object for examination are required. It is provided according to the invention that the integration time for recording each angular position depends on the geometry of the object for examination and the adsorption properties of the object for examination in this angular position.
