  Global scout views have been previously used to reduce interior
reconstruction artifacts in high-resolution micro-CT and C-arm systems. However
these methods cannot be directly used in the all-important domain of clinical
CT. This is because when the CT scan is truncated, the scout views are also
truncated. However many cases of truncation in clinical CT involve partial
truncation, where the anterio-posterior (AP) scout is truncated, but the
medio-lateral (ML) scout is non-truncated. In this paper, we show that in such
cases of partially truncated CT scans, a modified configuration may be used to
acquire non-truncated AP scout view, and ultimately allow for highly accurate
interior reconstruction.
