Image quality and X-ray dose for translation reconstruction overview imaging of the spine, colon and legs

Abstract Overview images of long parts of the human anatomy (spine, colon, legs) can be generated from a translated series of digital image intensifier (II) X-ray images using dedicated match-and-paste algorithms. The purpose of this study is to clarify the relation between the X-ray dose of the overlapping image series and the resulting image quality (contrast and noise) and image geometry of the overview image. We describe the entire acquisition protocol, but focus on the specific optimizations for translation reconstruction.
