Direct coronal CT scanning for the body.
A direct coronal CT scanning technique for the trunk, named "Quasi-Coronal" CT, is presented and its usefulness demonstrated with clinical examples. Patients are placed in the lateral position on a wide plate laid on the scanner bed and instructed to assume various special postures. An important concept of this technique is to obtain the tomograms in which target organs with predominant longitudinal orientation are directly imaged in the coronal plane. An analysis of artifacts due to "Out of Field" objects is presented. When properly performed, "Quasi-Coronal" CT can provide useful additional information, despite having some limitations.
