A less than optimal AP oblique foot projection demonstrates closed lateral cuneiform-cuboid, navicular-cuboid, and third through fifth intermetatarsal joint spaces. The fourth metatarsal tu-bercle is demonstrated without fifth metatarsal superimposition.
 
  a. The patient's foot was overrotated.
  b. The patient had a high longitudinal arch and a 45-degree oblique was obtained.
  c. A 10- to 15-degree proximal central ray angle was used for the projection.
  d. The patient had a low longitudinal arch and a 30-degree oblique was obtained.
