Abstract
A computed tomography (CT) apparatus and a method for identifying photon-counting detectors that are polarized due to high flux, thereby rendering the photon-counting detector inoperable. The data obtained from the photon-counting detectors that are determined to be polarized is skipped during an image pre-reconstruction phase. The data is further assigned a weight of zero during an image reconstruction phase in order to avoid imaging artifacts in the reconstructed CT image.
