    摘要: In a method for the creation of a dental 3D radiograph of at least a subregion, forming a volume, of an object using an X-ray apparatus, the volume is recorded as a 3D radiograph from a plurality of projected images during a revolution around the object. At least a part of the object is displayed in a graphical representation before the radiograph of the volume is created, the position of the graphical representation relative to the current position of the apparatus and the patient being known. The volume to be radiographed, governed by the positioning of the object relatively to the apparatus and by the choice of the settings data and/or control data, is placed in the graphical representation in an at least approximately correct position, and when there is a change in position and/or size of the volume to be radiographed within the graphical representation, the settings data and/or control data for the creation of the 3D radiograph are defined.
