Size 1024 mm x 1024 mm
       Nominal resolution:
            128 x 256
            Pixel size 8 x 4 mm2
       Low resolution:
            128 x 128
            Pixel size 8 x 8 mm2

       Right detector:
       Same orientation of tubes, same size of pixels
       Only 96 tubes instead of 128 tubes in the main detector
