  1. 2. 15° caudal PA projection of the skull demonstrating the sinuses well and any orbital fractures.
  2. 4. 30° caudal AP projection of the skull to assess for fractures and Paget’s disease with visualisation of the petrous ridges.
  3. 5. View demonstrating the radial head when querying fracture or dislocation.
  4. 10. PA projection of the skull with the OML at 37° to assess for facial fractures.
  5. 12. Commonly used in paediatric imaging to assess for slipped capital femoral epiphysis and perthes disease.
  6. 13. Hands are positioned like they’re catching a ball to assess for rheumatoid arthritis.
  7. 15. Visualisation of the lateral and medial malleoli of the distal fibula and tibia in profile with opened tibiotalar joint.
