Abstract

In a known type of tomosynthesis x-ray source and x-ray detector are linearly moved and x-rays images are taken for a large number of positions, the images being reconstructed to give a 3D image record. According to the invention x-ray source and x-ray detector are swiveled and a sequence of x-rays is subsequently taken again, x-ray source and x-ray detector again being moved in a straight line. One drawback of simple tomosynthesis with movement in a straight line is suppressed thereby, the drawback being that the quality of reconstruction is particularly poor in a certain direction.
