To obtain open tarsometatarsal and navicular-cuneiform joint spaces on an AP axial foot projection, the foot should be positioned flat against the IR (1) and the central ray should be angled 10 to 15 degrees proximally (3). Aligning the foot, ankle, and lower leg (2) is a general positioning practice but not specifically necessary for this projection. A compensating filter over the toes (4) is not needed for this projection.
