Skull (Towne view)

The Towne view is an angled AP radiograph of the skull.

  • the patient's nuchal ridge is placed against the image detector
  • dorsum sella overlies the foramen magnum
  • image size: 24 x 30 cm
  • the beam travels anterior to posterior (AP) direction, with ~30-40° of angulation from ~5 cm above the level of the nasion, toward the foramen magnum
  • source-to-image distance: 40" (100 cm)
  • 80-85 kVp at 25 mAs (or AEC)
  • grid is used
  • occipital bone and posterior fossa space better evaluated than with a nonangulated AP view, which would have more skull base and facial bone overlap
  • better than a conventional AP view for evaluating an occipital plagiocephaly involving the lambdoid suture 
  • may be a useful additional view for evaluating skull fractures 1
