Technical Note: On the accuracy of parametric two‐parameter photon cross‐section models in dual‐energy CT applications
PURPOSE: To evaluate and compare the theoretically achievable accuracy of two families of two‐parameter photon cross‐section models: basis vector model (BVM) and modified parametric fit model (mPFM). METHOD: The modified PFM assumes that photoelectric absorption and scattering cross‐sections can be...
