Method for recording a large-area x-ray image

A method for provision of a large-area x-ray image of an object mounted by means of an object platform and provision of additional synthetic x-ray projections, comprising:

• recording a plurality of x-ray projections by an x-ray device, wherein the plurality of x-ray projections are recorded during a linear movement of the object platform and/or the x-ray device;
• preparing at least one tomographic volume from the plurality of x-ray projections;
• preparing at least one first synthetic forward projection from the at least one tomographic volume, wherein the at least one synthetic forward projection yields a large-area x-ray image;
• representing the large-area x-ray image on a suitable display device;
• receiving a selection and/or marking of an area of interest within the large-area x-ray image;
• calculating a movement of the x-ray device and/or the object platform based at least in part on the received area of interest under the stipulation that after executing the movement, a projection geometry relative to the object results, which then enables the preparation of an x-ray projection that at least approximately corresponds to at least one second synthetic forward projection comprising the area of interest;
• preparing at least one second synthetic forward projection comprising the area of interest;
• and
• representing the at least one second synthetic forward projection on a suitable display device;
• wherein the at least one second synthetic forward projection is prepared in a projection geometry that corresponds to a current orientation of the x-ray device in space after the movement.
