Abstract
Official abstract text for this publication.
The invention relates to a detection apparatus comprising a filter ( 20 ) for filtering a conical radiation beam ( 4 ) such that at least a first region ( 22 ) and a second region ( 23 ) of the radiation beam are generated having different energy spectra, wherein the first region of the radiation beam illuminates a first detector area ( 25 ) on a detection surface ( 21 ) of a detector, thereby generating a first set of detection values, and the second region of the radiation beam illuminates a second detector area ( 26 ) on the detection surface, thereby generating a second set of detection values. For example, by using the filter the detection apparatus can be used as dual-energy computed tomography apparatus, wherein, for instance, a standard computed tomography apparatus can be transformed to a dual-energy computed tomography apparatus by adding the filter to the standard computed tomography apparatus, preferentially without modifying the radiation source and the detector.
First claim
Opening claim text (preview).
The invention claimed is: 1. A detection apparatus, the detection apparatus comprising: a radiation source configured to generate a conical radiation beam for traversing a region of interest within an examination zone; a detector with a homogenous detection surface configured to generate detection values being indicative of the radiation beam after having traversed the region of interest; a moving unit configured to move the radiation source and the region of interest relative…
