METHOD FOR CORRECTING IMAGE ARTEFACTS CAUSED BY DEFECTS IN A FLUORESCENT X-RAY STORAGE LAYER, AND X-RAY DEVICE

摘要

The invention relates to a method for correcting image artefacts (7) caused by defects in a fluorescent x-ray storage layer (4), said method comprising the following steps: a surface of incidence of the fluorescent x-ray storage layer (4) is irradiated with a pre-determined homogeneous x-ray intensity; said surface of incidence is irradiated with a pre-determined homogeneous light intensity; the intensity of the emitted scintillation light is measured for each pixel of a matrix (6a, 6b) describing the surface of incidence, and the defect pixels DBi,j corresponding to a defect are determined; and the pixels RBi,j corresponding to the defect pixels DB i,j and pertaining to a raw image RB are corrected by means of interpolation.
