ABSTRACT:
In a method and examination apparatus for generating three-dimensional, multiply resolved volume images of an examination subject on the basis of two-dimensional projection images that can be registered with the apparatus, as radiation images obtained with a radiation source and a radiation receiver in an exposure procedure of the examination subject, a set of two-dimensional projection images is registered, one part of the set being registered with low resolution and one part of the set being registered with high resolution, transforming the high-resolution projection images are transformed so as to have the same scale, the same sampling rate and the same resolution as the low-resolution projection images (downscaling), and a three-dimensional volume image with low resolution is generated on the basis of the low-resolution projection images as well as the transformed projection images and a high-resolution volume image is generated on the basis of the high-resolution projection images.
