摘要： Mixtures of linear organopolysiloxanes of the general formula 1 for R3SiO—(SiR2O)n—SiR3  (1) are produced by a process in which organochlorosilanes of the general formula 2 R4−ySiCly  (2) where R is identical or different and is a hydrogen atom or an unsubstituted or substituted hydrocarbon radical having from 1 to 18 carbon atoms, Y is 1 or 2, and n is 0 or an integer from 1 to 50, are reacted continuously in a closed circulation system with water which may, if desired, have been acidified with hydrochloric acid, where the HCl concentration in the hydrochloric acid discharged is less than 25% by weight. Low molecular weight oligomer mixtures substantially free of both cyclic organosiloxanes and organosilicon compounds containing Si—Cl are economically produced.

摘要： The invention relates to a computer tomography method in which a periodically moving object, in particular an organ of the body, is irradiated by a cone-shaped beam cluster (4) along a trajectory which runs on a cylindrical surface. The radiation transmitted through the object is measured by means of a detector unit (16), and at the same time the periodic movement of the object is recorded. In order to reconstruct the absorption distribution of the object, the measured values or the corresponding beams are rebinned to form a number of parallel projections, where for each of these projections a measured value is determined whose beam irradiates the object. The point in time at which this measured value was acquired is allocated to the respective projection. For the reconstruction, which may for example be carried out using a filtered back-projection, only projections whose allocated points in time lie within a predefined, specific time range (H1) within a period of the object movement are used.

摘要： The invention relates to a computer tomography method in which a radiation source moves relative to an examination region along, in particular, a helical or circular trajectory. Measured values are acquired by a detector unit and a CT image of the examination region is reconstructed from these measured values. In the reconstruction, a complementary measured value, whose ray is oriented parallel to the ray of the respective measured value that has been acquired but in the opposite direction thereto, is determined for each of at least some measured values that lie within a reconstruction window. Redundant measured values are used to calculate the complementary measured values, with the help in particular of John's equation. The measured values for which complementary measured values have been determined are each replaced by a sum comprised a measured value that has been weighted and a complementary measured value that has been weighted, and a CT image is reconstructed, in particular by an exact method of reconstruction, from the replacement measured values, and where appropriate from acquired measured values, that lie within the reconstruction window.

摘要： A method of determining a relative position of first and second imaging devices includes setting an image of a group of mutually different reference patterns and a basic pattern on an imaging medium, with the second imaging device. Each reference pattern of the group is assigned uniquely to one relative position. An image of at least one test pattern is set over the basic pattern by the first imaging device, for forming a combination pattern. A reference pattern having an area coverage coinciding with an area coverage of the combination pattern is identified from the group of reference patterns. A relative position associated with the identified reference pattern of the group of reference patterns is then identified. A printing form exposer, a printing unit, a printing unit group and a printing press for performing the method are also provided.

摘要： The invention relates to a computed tomography apparatus whose radiation source emits a conical radiation beam and is capable of scanning the examination zone along a trajectory in the form of a helix. The detector unit that is connected to the radiation source consists of a plurality of spatially separated detector segments that are mutually offset in the axial direction and each of which is arranged in such a manner that a projection onto the helix covers at least two neighboring turns of the helix. A CT image having an improved and spatially more uniformly distributed signal-to-noise ratio can be reconstructed from the CT data acquired by means of such a detector unit.

摘要： Method and device for forming a 3D image of an object to be examined by combining at least two reconstruction images, acquired by an X-ray device, by weighted addition. Specifically, each reconstruction image is weighted with a respective weighting function which describes at least approximately the distribution of noise and/or the distribution of artifacts in the reconstruction image. The image quality of the resultant three-dimensional image is thus significantly improved.
