The invention relates to a method for the creation of a panoramic tomographic image of an object ( 10 ) by means of X-rays, in which a digital X-ray-sensitive image detector ( 14 ) is moved relatively to the object to be X-rayed ( 10 ) and image data of the object ( 10 ), for a first layer ( 15 ) of the object ( 10 ) are summated to a first storage area ( 21.1 ), wherein the summation is carried out after a predefined first time interval (Deltat<SUB>1</SUB>) with a predefined first line offset (Deltas<SUB>1</SUB>). Image data for a second layer ( 16 ) of the object ( 10 ) are summated to a second storage area ( 21.2 ), which summation is performed after a predefined second time interval (Deltat<SUB>2</SUB>) with a predefined second line offset (Deltas<SUB>2</SUB>). The invention further relates to a digital X-ray image acquisition device ( 1 ) for the creation of panoramic tomographic images of an object ( 10 ), comprising an X-ray-sensitive image detector ( 14 ), a first and second storage area ( 21.1, 21.2 ) for storing data, and a first and second linker ( 20.1, 20.2 ) for linking image data.
