摘要 |
To enhance image acquisition and speed up the examination during x-ray examinations, the present invention relates to an X-ray apparatus for three dimensional imaging and in particular for tomosynthesis examination, comprising a means for obtaining a set of projection images of a body part, a reconstruction means for reconstructing a three-dimensional image volume, memory for storing the projection images, and a control means. The reconstruction arrangement is arranged to reconstruct a three-dimensional image volume from data in the projection images in the memory, the reconstruction arrangement being arranged to reconstruct a first and a second image volume, wherein the second image volume is reconstructed having lower resolution than the first image volume.
