Abstract: Modular generator system comprising at least two generator types which are composed of a plurality of generator components and differ with regard to their equipment and/or functions. The generator components comprise a power supply and an inverter for generating an output energy for an electrosurgical instrument. The generator types are each of modular design with a plurality of modules: (i) at least one uniform base module having a communication unit, and (ii) at least one individual module which may differ depending on generator type. Individual modules can be a module for the power supply, a module for the inverter, a module for the output connection. Different generator types differ with regard to their individual module equipment. By virtue of such a two-tier module concept, namely uniform base module and differing individual modules, a maximum number of variants can be achieved with a minimum number of different modules.

Abstract: A method, device, and computer program product for capturing projection images of an object are provided. An x-ray beam source is moved by a control unit on a path into a plurality of positions, in which an x-ray beam is transmitted. An x-ray beam detector is moved by the control unit into a plurality of positions, in which the x-ray beam, penetrating the object, is detected. The x-ray beam source and/or the x-ray beam detector are moved on a calculated path around the object, at a constant distance between the x-ray beam source and the x-ray beam detector or the object. The path is described by an nth degree polynomial and determined by the control unit through an optimization of a path along the central x-ray beam. The polynomial is selected such that a safety clearance with respect to the object is maintained and a distance between the x-ray beam detector and the object is minimized.

The X-ray tube assembly is attached to a motor-driven movable stand arm and can be displaced using a control unit. The stand base of the movable stand can be positioned in a spatially fixed manner, so that it has a defined fixed position relative to the radiation detector.

The radiation source is moved relative to the object to be imaged into multiple positions in a first movement on a first track which lies on a first plane in order to capture images, at least one image being captured in each said position. The three-dimensional image is reconstructed from the captured images by the analyzing unit. The radiation source and the radiation detector carry out a second movement relative to the object to be imaged on a second track which is at least partly different from the first track at the same time as the first movement in order to reduce artifacts in the image, said artifacts being generated due to radiation absorption. In the process, the first movement and the second movement are superimposed.
