Figure 2.

Forward rebinning: the values on the rebinned detector grid (right) are generated by linear interpolation from the values on the original detector grid (left). The filtering lines are sampled such that interpolation needs to be done only in vertical direction. In horizontal direction, both detector grids coincide. The figure shows a case with five filtering lines. As illustrated, the detector values that are at the two positions (crosses “+”) within the dashed circle on the left are interpolated to produce the rebinned detector value within the dashed circle on the right.
