The present disclosure relates to a procedure for generating fluoroscopic images for the reconstruction of a volume in a flat object using an X-ray system, which has three imaging components, namely a tube, a detector and a manipulator, located between them, on which the object is fixed. The object extends multiple times further in two dimensions than in its third dimension. The tube has a focus, which, in a central position of the tube, forms the coordinate origin of a Cartesian coordinate system, and which emits an X-ray. The vector from the tube through the volume forms the x axis of the coordinate system and the z axis is perpendicular to a vector formed through the thickness. The manipulator is rotated about a rotational axis, which is perpendicular to the x axis, runs parallel to the z axis and is displaceable parallel to the x axis.

Procedure for generating fluoroscopic images for the reconstruction of a volume in a flat object using an X-ray system

A method for the reconstruction of a test part in an X-ray CT method in an X-ray CT system, which has an X-ray with a focus, an X-ray detector, and a manipulator which moves the test part within the X-ray CT system. To generate recordings of the test part in various positions, the manipulator travels a predefinable parameterizable path-curve and makes recordings at triggered positions. For each recording, the position of the manipulator is determined and the respective associated projective geometry is calculated. Thereafter, a further path curve is followed having different parameters from the preceding path curve. The path curve is determined iteratively by means of an optimization algorithm, at the value of which the quality function is minimal. For each test part, a CT reconstruction is carried out by means of a suitable algorithm with reference to the allocation of the individual recordings to the respective projective geometry.
