4. 40" FFD
5. Central Ray: mid ankle joint

2. Patient supine with foot rotated in 5-15 degree to place intermalleolar line parallel to film with foot flexed.
3. Table top exposure
4. 40" FFD
5. Central Ray: mid-ankle joint
Lateral
1. 8 x 10 extremity cassette
2. Patient lateral turned toward affected side until leg and foot are in a true lateral position (may need knee support).
