Abstract: A method for generating a panoramic layer image of an object to be imaged, by employing a 2D panoramic X-ray device, the object being imaged by projecting X-rays generated by an X-ray source through the object in a projection direction and recording the X-rays with an X-ray detector. Several 2D X-ray projection images are continuously recorded from various imaging directions while the X-ray source and the X-ray detector move around the object. At least one panoramic layer image is calculated from the recorded 2D X-ray projection images using a reconstruction method. The panoramic layer image is calculated by selecting and employing at least one partial area from at least two 2D X-ray projection images in relation to an active sensor area.
