Estimate the reduction in scatter produced by a 1 mm collimated x-ray scanning system (like in Figure) compared with a conventional x-ray beam. Assume that the object is 100 x 100 x 100 cm phantom that is placed on the image detector and that the entire phantom is imaged. Make your calculation based only on the geometrical efficiency at the center of the detector. Report the ratio of scatter using the slit to that without it.
