摘要： A turbocharger (10) with a cross flow turbine (30) where exhaust gas passes through a cross flow turbine wheel (18) on its outer diameter. A cross flow turbine (30) has radial exhaust gas inlet and outlet. Cross flow turbines (30) are suited for variable turbine geometry, including with a single guide vane (44) or multiple guide vanes in the turbine inlet (34) to control variable flow and thus performance of the turbine stage. Cross flow turbines (30) allow reduced size and excellent packaging options, such as a single or dual cross flow turbine wheel (18) between two compressor wheels (12).

摘要： To make optimum use of an x-ray image recording system with an x-ray C-arm, which has an x-ray radiation source and an x-ray detector and can be pivoted about any axis, 2D axis lines are plotted in two x-ray images of an object to be imaged more precisely and these 2D axis lines are used to define a 3D axis line and the x-ray image recording system is set so that it can be directly pivoted precisely about this 3D axis line. A sequence of x-ray images is then recorded in positions of the x-ray C-arm, between which the same can be pivoted about this defined axis. This displays the object optimally.
