Abstract
The present invention discloses a method to calibrate a photon counting detector (3). An absorption filter (7) is moved transversely through a photon beam (8) emitted towards the detector (3) to average out the effect of inhomogeneties of the absorption filter (7). The invention also relates to an absorption filter assembly and an imaging device (1) comprising such an absorption filter assembly.
