The invention combines information from two different energies to create a greatly improved visualization over commonly available dual energy imaging blending techniques. Dual-energy CT may provide additional diagnostic information to the physician, but the question arises on how to best illustrate it. In conventional single energy CT, patient data is presented to the physicians using very well understood organ specific window and level sets. Presentation of dual-energy CT is less clear because both signal, noise, and spatial resolution must be balanced to optimally display unique pathologies in various organs with different vascular patterns and heterogeneity. This invention provides a of organ specific non-linear mixing algorithm that optimizes the blending of both the low and high kV information in a way that visualizes the benefits of both energies in a single image.
