Optimization of extraoral panoramic images through model-based prior knowledge of the patient's jaw arch form

Abstract

The disclosure relates to a method including: (S1) Determining the jaw arch form as a model-based prior knowledge about the anatomy of a patient based on one or more previous panoramic images or 3D images or one or more optical 3D scans of the patient; (S2) Determining a patient-specific x-ray device imaging trajectory for the panoramic image of the patient; (S3) Performing the imaging on the basis of the determined patient-specific x-ray device imaging trajectory to acquire imaging data; (S4) Adjusting reconstruction parameters according to the determined patient-specific x-ray device imaging trajectory; (S5) Determining the patient-specific focal curve for the panoramic image of the patient to be produced by using the model-based prior knowledge; (S6) Reconstructing the panoramic image using the acquired imaging data, the adjusted reconstruction parameters including the determined patient-specific focal curve, and a layer to be imaged which overlaps with the determined jaw arch
