Patent ID: 11963812

Abstract:
The invention relates to a method for producing a panoramic tomographic image (1, 11, 60) of an object (2) to be recorded using a 2D panoramic X-ray device (3), in the course of which X-rays (4) produced by means of an X-ray source (5) irradiate the object (2) and are acquired by means of an X-ray detector (7), wherein, during a movement of the X-ray source (5) and the X-ray detector (7) around the object (2), a number of 2D X-ray projection images (30) are acquired from different acquisition directions (6). A first panoramic tomographic image (1) is calculated from the acquired 2D X-ray projection images (30) using a reconstruction method, wherein the acquired 2D X-ray projection images (30) are modified using a modification method, wherein, from the modified 2D X-ray projection images (40, 50) and using the reconstruction method, a second panoramic tomographic image (11) is calculated with a higher weighting of artifacts (20) relative to anatomical structures (17, 18, 19), wherein a third panoramic tomographic image (60) with significantly reduced artifacts is calculated.
