In a method for the creation of a dental 3D radiograph of at least a subregion, forming a volume (42, V1, V2), of an object (14) using an X-ray apparatus (1), said volume can be recorded as a 3D radiograph from a plurality of projected images during a revolution around said object. At least a part of the object (14) is displayed in a graphical representation (40, 71, 72, 73) before the radiograph of the volume (42, V1, V2) is created, the position of the graphical representation (40, 71, 72, 73, 74) relative to the current position of the apparatus and the patient being known. The volume (42, V1, V2) to be radiographed, governed by the positioning of said object (14) relatively to the apparatus and by the choice of the settings data and/or control data, is placed in said graphical representation (40, 71, 72, 73, 74) in an at least approximately correct position, and when there is a change in position and/or size of the volume to be radiographed (42, V1, V2) within the graphical representation (40, 71, 72), the settings data and/or control data for the creation of the 3D radiograph are defined.
