ABSTRACT:
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.
