A multi-dimensional representation of an object is obtained in that first and second pictures of the object illuminated using an X-ray source are created using a sensor that is located, in relation to the X-ray source, behind the object in a preferential direction defined by the relative positions of the object and of the sensor. A distance in the preferential direction between the X-ray source and the object is different in the first picture than in the second picture. The multi-dimensional representation of the object is obtained by combining the first and second pictures.

Apparatus and method for non-rotational computer tomography

In an X-ray computer tomograph and a method for examining a component by means of X-ray computer tomography, the component carries out a movement relative to a radiation source detector unit in at least two degrees of freedom of movement, so at least one trajectory can be produced which spans a three-dimensional space. Since the X-radiation has a three-dimensional radiation geometry, volume data can be rapidly obtained and precisely reconstructed to form a three-dimensional X-ray image. The component can be geometrically measured by means of a geometry detection unit.

X-ray computer tomograph and method for investigating a component by means of X-ray computer tomography

In an X-ray computer tomograph and a method for investigating an object by means of X-ray computer tomography, to improve the image quality, a first intensity of the X-ray radiation between an X-ray source and the object is measured by means of a first intensity measurement device () and a second intensity of the X-ray radiation between the object and the X-ray detector outside a projection region of the object is measured by means of a second intensity measurement device. A scattered radiation correction factor is calculable by means of the measured intensities to reduce the scattered radiation.

X-ray computer tomograph and method for investigating an object by means of X-ray computer tomography

A method is for restoring a signal of a defective channel of a beam detector, which has a multitude of channels and by means of which projections are recorded from different directions of projection. The channels of the beam detector each have a detector element with channel electronics connected downstream thereform. The signal of the defective channel is restored while using neighboring signals of an M-neighborhood of the same projection and from adjacent signals of an M-neighborhood of additional projections.
