Systems, methods and computer instructions for displaying multi-energy data are provided. Certain methods include: receiving multi-energy data from an operably connected data source; displaying the multi-energy data as an image via a graphical user interface; selecting a region of interest in the displayed image; and displaying information regarding the region of interest via the graphical user interface. Certain methods include: (1) displaying a graph that includes an attenuation line depicting radiodensity versus energy level; (2) displaying a material density graph of a region of interest and/or of results of segmenting a region of interest; and/or (3) displaying information in a window configured to be movable about an interface. Certain methods include: receiving multi-energy data from an operably connected data source; and displaying the multi-energy data as a fused image via a graphical user interface.
