Abstract
The invention relates to a computed tomography apparatus which includes a scanning unit which is rotatable, relative to an examination zone ( ), around an axis of rotation ( ) which extends through the examination zone ( ), and also includes a radiation source (S) for generating a primary fan beam ( ) which traverses the examination zone ( ), and a two-dimensional detector array (D) which includes a plurality of detector elements and a part of the measuring surface of which detects primary radiation from the primary fan beam ( ) whereas an other part of its measuring surface detects scattered radiation produced in the examination zone ( ). In order to avoid reconstruction artefacts as much as possible in a computed tomography apparatus of this kind, in accordance with the invention it is proposed to arrange a modulation unit ( ) between the radiation source (S) and the examination zone ( ) in order to realize a temporally and spatially periodic modulation of the primary fan beam ( ).
