  • Dorsal recumbency
  • Ensure collar removed
  • Ensure ET tube running straight if under GA
  • Use a cradle to support body
  • Position with skull perpendicular to cassette
  • Centre in midline level with the orbits, adjusting depending upon skull shape
  • Ensure L/R marker in primary beam.

What to look for

  • When looking for skull to be perpendicular to table top use the mandible and ventral border of the skull, as these tend to be less distorted by head shape variations.
