All images show the reconstruction of the raw (left) and preprocessed (right) detector image of the source at source-to-mask distance of 20 mm at the 20 mm plane. The top row shows the reconstructions from MURA Decoding while the bottom row shows the 3D-MLEM results. Notice the higher background noise in the reconstructions from the raw detector image. For a better comparison all images were normalized to the pixel intensity range of 0 to 1
