摘要： The present invention relates to a method of producing a panoramic image, characterized in that it comprises the following steps: (S1) Determining the jaw arch form (11a) as a model-based prior knowledge about the anatomy of a patient (10) 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 (12) for the panoramic image of the patient (10) to be produced by using the model-based prior knowledge so that the jaw arch from (11a), in particular the position of the teeth (11b) can be optimally exposed and imaged; (S3) Performing the imaging on the basis of the determined patient- specific x-ray device imaging trajectory (12) to acquire imaging data; (S4) Adjusting reconstruction parameters according to the determined patient-specific x-ray device imaging trajectory (12); (S5) Determining the patient-specific focal curve (14) for the panoramic image of the patient (10) to be produced by using the model-based prior knowledge so that the jaw arch form (11a) in particular the position of the teeth (11b) can be optimally reconstructed; (S6) Reconstructing the panoramic image using the acquired imaging data, the adjusted reconstruction parameters including the determined patient- specific focal curve (14), and a layer to be imaged which overlaps with the determined jaw arch form (11a), wherein the patient-specific focal curve (14) lies within said layer to be imaged; (S7) displaying the reconstructed panoramic image.
