Abstract

A method for selective imaging of body structures includes acquiring first image data set by a first tomography method, acquiring a second image data set by 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, reconstructing an image from the first image data set, and selecting the image data to be reconstructed from the first image data set using the second image data set. In order to achieve a higher imaging quality while using a low-resolution tomography method, image reconstruction of the image data selected from the first image data set 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.
