ABSTRACT:
A system and method are presented for reprojecting images generated by a back-projector. The image data is processed to distinguish hard and soft tissue and then is transmitted to the normal input of the back-projector. Pseudo-projections (reprojections) are obtained at the normal output of the back-projector. Each image row is fed into the input of the back-projector as a normal projection. The "image" generated by the back-projector is now one projection. In order to generate the required amount of reprojections "L", the image is supplied to the back-projector "L" times. Each time the image is presented with constants, such as the reprojection angle associated with the specific reprojection. The reprojections at the back-projector output are combined in a feed-back circuit with the original projections to correct for artifacts, such as polychromatic artifacts.
