Abstract
The invention relates to a method for producing a panoramic tomographic image () of an object () to be recorded using a 2D panoramic X-ray device (), in the course of which X-rays () produced by means of an X-ray source () irradiate the object () and are acquired by means of an X-ray detector (), wherein, during a movement of the X-ray source () and the X-ray detector () around the object (), a number of 2D X-ray projection images () are acquired from different acquisition directions (). A first panoramic tomographic image () is calculated from the acquired 2D X-ray projection images () using a reconstruction method, wherein the acquired 2D X-ray projection images () are modified using a modification method, wherein, from the modified 2D X-ray projection images () and using the reconstruction method, a second panoramic tomographic image () is calculated with a higher weighting of artifacts () relative to anatomical structures (), wherein a third panoramic tomographic image () with significantly reduced artifacts is calculated.
