Figure 2

(a) Virtual monoE images at 50 keV and (b) 200 keV of the three basis compositions sodium chloride (Na\(_0\)), iomeprol (I\(_0\)) and eosin Y disodiumsalt (E\(_0\)). (c) The linear relationship of each basis material is shown for different concentrations mixed together in aqueous solution. Linear regressions were then created for the linear dependencies, allowing the endpoints of each basis material to be better determined computationally and with greater statistical accuracy. (d) The way of iodine optimization along a characteristic optimization path (red vector) is shown for specimen 2, 4 and 5. The exact results found by the algorithm are shown in Table 1.
