1. A method for the selective imaging of body structures, in which method a first image data set is acquired by means of a first tomography method, a second image data set is acquired by means of a second tomography method which has a resolution which is higher than that of the first method, the image data of the first and the second image data set coinciding at least partly in space, an image is reconstructed from the first image data set, and the image data to be imaged is selected from the first image data set by means of the second image data set, wherein for the reconstruction from the first image data set first at least one image region to be imaged is selected from the second image data set, and subsequently the image reconstruction is calculated from the image data of the first image data set which are situated in the selected image region.
