(a) Static flat-field correction Istatic−FF of 10× radiography of the JIMA RT RC-02 target. (b) Dynamic flat-field correction IDMM − FF of the same FOV and (c) transmission values plotted through both images in the same empty region (averaged over a 50 pixel line width). Both radiographs were taken at 25 keV and at a distance of 15 mm from the detector. The red rectangles in (a) and (b) show the ROIs used for CNR/SNR calculations, centered on tungsten lines (solid rectangle) and on the background (dashed lines). |
