The invention concerns a method for obtaining operating parameters for x-ray imaging a patients maxillofacial region, the method comprising: -identifying a patients maxillofacial first region of interest ROI1, -determining a height of a horizontal plane of said patients maxillofacial first region of interest ROI1 when the patient is in an occlusion position or bites a patient positioning accessory, said horizontal plane passing through the teeth and the bones of the jaw, -acquiring through a slit-shaped collimator window a first set of data relative to said patients maxillofacial first region of interest ROI1 including the horizontal plane using x-ray CBCT imaging and a first x-ray dose, said first set of data being suitable for generating a CBCT slice, -reconstructing the CBCT slice comprising the horizontal plane based on the first set of data relative to the patients maxillofacial first region of interest ROI1, -obtaining operating parameters for an x-ray imaging apparatus based on the reconstructed CBCT slice in view of acquiring a second set of data of a patients maxillofacial second region of interest ROI2 using a second x-ray dose, the first x-ray dose being lower than the second x-ray dose.
