A method for digital volume tomography imaging in the dental region with an X-ray apparatus, comprising the following steps: (a) A patient is positioned in the X-ray apparatus; (b) A 3D scout image of the patient is taken with reduced dose and with one of a plurality of predefined volume sizes and a predefined center of rotation of the X-ray apparatus; (c) A practitioner marks a tooth on the 3D scout image for which he or she wants high-resolution information with an enveloping geometry; (d) A software uses a position of the enveloping geometry to determine the available centers of rotation of the X-ray apparatus at which this enveloping geometry can be imaged, and uses reference points (13a-13h) of the enveloping geometry to calculate the imaging positions (13a'-13h') on an X-ray detector of the X-ray apparatus for each of the available centers of rotation; (e) Based on the imaging positions (13a'-13h'), a center of rotation (11") is selected from the set of available centers of rotation, and aperture positions (14a-d) for a high-resolution image and detector areas of the high-resolution image to be irradiated are determined for this center of rotation (11"); (f) The previously determined aperture positions (14a-d) and the detector areas to be irradiated are transmitted to the X-ray apparatus and the high-resolution exposure is now performed with the center of rotation (11") selected from the set of available centers of rotation and the transmitted aperture positions (14a-d); (g) The high-resolution image is reconstructed and a corresponding newly recorded high-resolution information is superimposed on the 3D scout image; (h) The 3D scout image, in which the previously marked enveloping geometry is superimposed by the high-resolution information, is displayed to the practitioner for diagnosis and further use.
