Claim 18:
19. A treatment method comprising:
receiving first measured projection data from a first source of radiation, the first source of radiation configured for imaging radiation;
receiving second measured projection data from a second source of radiation, the second source of radiation configured for at least one of imaging radiation or therapeutic radiation, wherein the second source of radiation has an energy level more than the first source of radiation;
combining the first measured projection data with the second measured projection data; and
reconstructing an image based on the combined data, wherein the reconstructing comprises at least one of:
correcting the second measured projection data using the first measured projection data;
correcting the first measured projection data using the second projection data; and
distinguishing different materials imaged in the combined data using the first measured projection data and the second measured projection.
