[Computer tomographic longitudinal sections of the trunk reconstructed from standard cross-sections (author's transl)].

Reduction in scan times and advances in the field of image reconstruction have made it possible to reconstruct the trunk from sequential coronal sections. For this purpose 8 mm cuts without overlap are suitable. There is consequently no increase in patient dose or in the scan time. Longitudinal sections can be reconstructed by a dedicated computer in about 10 minutes and cross sections can be evaluated in more detail. The longitudinal reconstructions provide better demonstration of organs and space-occupying lesions in their craniocaudal extent. This extension of the diagnostic spectrum is of value to the diagnostician and particularly to radiotherapists and surgeons during treatment planning.
