Abstract:ObjectivesTo produce a copper (Cu) stepwedge with aluminum (Al) equivalent mean gray values
(MGV).Material and MethodsThe thicknesses of Cu steps that were equivalent to those of the Al were
formulated using the X-ray attenuation properties of the materials. The Al and
fabricated Cu stepwedges were radiographed, but the MGVs of the Cu stepwedge were
mismatching to those of the Al. Using a mathematical function to adjust the pixel
MGV of Cu stepwedge to those of the Al, new Cu stepwedges were created. In
