Abstract: A method for operating a medical imaging apparatus includes acquiring a first image data set of a region of interest of the patient; automatically evaluating the first image data set using at least one evaluation algorithm yielding evaluation information, regarding at least one type of findings, describing a presence of at least one finding of the type requiring the acquisition of a second image data set and at least one imaging parameter for the second image data set; automatically notifying a user, upon the evaluation information indicating the presence of a required second image data set, of the required acquisition of the second image data set; and acquiring the second image data set acquiring the second image data set after confirmation of acquisition of the second image data set by the user, in a same examination process, using the at least one imaging parameter of the evaluation information.

Abstract: A cell includes a transparent covering element arranged at a top side of the cell, an interior arranged below the covering element, the interior being partly filled with an electrolyte, and a semiconductor absorber arranged in or at the electrolyte. Furthermore, the cell includes one or more counterelectrodes arranged above the semiconductor absorber in the electrolyte and electrically connected to a back electrode arranged at a rear side of the semiconductor absorber facing away from the covering element, and one or more membrane enclosures, wherein a counterelectrode in each case extends within a membrane enclosure. One or more channel spaces are formed between an electrolyte surface and an underside of the covering element, the one or more channel spaces extending along one or more partial regions of the underside of the covering element and being usable for guiding away a first gas formed in the interior of the cell.

Abstract: A system includes a gantry of a medical imaging apparatus. In an embodiment, the gantry includes an X-ray source, and a radiation protection booth, which can be installed or suspended relative to the gantry.

Abstract: A polyunsaturated hydrocarbon, 6-(2,7-octadienyl)-1,4-cyclooctadiene. 6-(2,7-Octadienyl)- 1,4-cyclooctadiene is prepared by reacting butadiene-1,3 in the presence of a catalyst system consisting of a nickel complex, an organic phosphite and dialkylaluminum alkoxide, removing unreacted butadiene-1,3 starting material and cyclooctadiene and cyclododecatriene material formed in the reaction from the reaction product obtained, and fractionally distilling 6-(2,7-octadienyl)-1,4-cyclooctadiene from the material obtained after the distillative separation of butadiene-1,3, cyclooctatriene and C12 compounds.

Abstract: A process for the isolation of high-boiling monomers from distillation residue formed in the cyclodimerization and/or cyclotrimerization of 1,3-butadiene after target products of cyclooctadiene, vinylcyclohexene and/or cyclododecatriene have been separated off, comprising extracting the distillation residue with a nonpolar or slightly polar solvent, separating off insoluble oligomers and polymers that have at least partly crystallized by mechanical separation, removing the extractant, and isolating the high-boiling monomers.
