Figure 4

  1. Inappropriately long topogram before a chest CT, with unnecessary exposure of additional parts of the body.

  2. Slicing of a cranial CT parallel to the base of the cranium to protect the orbits. The topogram also shows a layer of lead rubber covering the lenses (authors’ images, UKGM, Giessen).
