摘要：
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.
