receiving first image data of a subject including an examination region, the first image data being pre-acquired, wherein the first image data maps the examination region;
generating a model dataset based on the first image data;
receiving second image data of the subject that is pre-acquired, wherein the model dataset and the second image data map at least a common part of the examination region at a second level of detail;
pre-aligning the model dataset and the second image data at a first level of detail below the second level of detail based on:
first features of a first class of features of the examination region that are mapped at the first level of detail in the model dataset and the second image data;
an acquisition geometry of the second image data with respect to the subject; or
a combination thereof;
registering the model dataset and the second image data at the second level of detail based on second features of a second class of features of the examination region that are mapped at the second level of detail in the model dataset and the second image data, wherein the second class of features is mappable at the second level of detail or above; and
providing the registered second image data, the registered model dataset, or the registered second image data and the registered model dataset as the result image data.
