    摘要： The present invention relates to a method and a device for capturing projection images of an object to be replicated (7). The device comprises a beam source (2), a beam detector (1) and a control unit (3), wherein the beam source (2) is moved by the control unit (3) on a path (12, 18, 27) into a plurality of positions, in which a beam emitted by the beam source (2) is transmitted in a cone beam shape around a central beam. At the same time as the beam source (2) is moved, the beam detector (1) is moved by the control unit (3) into a plurality of positions, in which the beam emitted by the beam source (2) and penetrating the object (7) to be replicated is intercepted to capture a projection image. The beam source (2) and/or the beam detector (1) are moved on a calculated path (13, 18, 20, 27) around the object (7) to be replicated, at a constant distance between the beam source (2) and the beam detector (1) or the object (7) to be replicated, which path is described by a polynomial nth degree and determined by the control unit (3) through an optimisation of a specified path along the central beam (19, 20), wherein the respective polynomial is selected in such a manner that a safety clearance with respect to the object (7) to be replicated is maintained and, at the same time, a distance between the beam detector (2) and the object (7) to be replicated is minimised. The invention further relates to a computer program product with a command sequence for actuating the device and performing the method.

    摘要： The invention relates to a multifunctional transporting system with multiple drivable transporting units (1), each of which has a coupling device (5) in a front and a rear region, said transporting units (1) being coupleable to one another and/or to a guiding vehicle (6) by means of the coupling device. The transporting units (1) can be removed or decoupled from the transporting system as closed units. For this purpose, the units have at least one handle (8) in addition to the couplings, said units being manually guidable by an operator (7) in the decoupled state by means of the handle such that the mail items to be transported can remain on the transporting unit until delivery without manually transferring or transporting. In particular, the delivery of parcels in the city-center area is implemented in a more efficient manner and thus in a more inexpensive and environmentally-friendly manner using the proposed transporting system.

    摘要： The present invention relates to an x-ray image recording system for recording x-ray projection images of alignment information for recorded x-ray projection images, comprising an x-ray tube 10 and an x-ray image detector 9 being arranged in the optical path of the x-ray tube for recording x-ray projection images of an object O that can be disposed and/or that is disposed between the x-ray tube and the x-ray detector in an imaging region B in a locally fixed manner, wherein the x-ray tube and the x-ray detector are disposed in a locally fixed manner relative to each other, and can be moved about the imaging region, at least in sections, a position sensor 2 being disposed relative to the x-ray tube 10 and the x-ray detector in a locally fixed manner, by means of said sensor the current alignment of the x-ray tube and the x-ray detector can be determined relative to a predefined reference direction R at the moment of recording of an x-ray projection image, and a storage unit 1a for storing recorded x-ray projection images together with the respective current alignment of the x-ray tube and the x-ray detector. The invention comprises a computer 1b being connected to the storage unit 1a for the purpose of data exchange, by means of said computer the position data of the x-ray projection image that are necessary for the calculation of the layered images of the reconstruction can be calculated from the stored, associated current alignment for the purpose of layered image reconstruction based on multiple recorded x-ray projection images for each recorded x-ray projection image utilized.
