For an anteroposterior (AP) projection of the toe, the central ray is directed perpendicular to the film and the metatarsophalangeal joint of the toe being examined. This ensures that the image captures the desired anatomical details without distortion. It's important to center the ray accurately to avoid overlapping structures and to achieve a clear radiographic image.
Llywelyn ap Dafydd died in 1287.
Cadwgan ap Bleddyn died in 1111.
Llywelyn ap Gruffydd was born in 1223 and died in 1282. He was the last independent ruler of Wales before its conquest by England. He was the grandson of Llywelyn the Great, and died at the Battle of Orewin Bridge near Cilmeri in central Wales, on December 11, 1282. Gruffudd ap Llywelyn, the man in question here however, was his father. He was imprisoned in the Tower of London with his eldest son, Llywellyn ap Gruffydd's elder brother, Owain. On 1st March 1244, while trying to escape, Gruffydd fell and was killed. It is said he hit the ground head first with such force that his head was pushed into his shoulders.
Robert ap Huw died in 1665.
Llinor ap Gwynedd was born in 1974.
The central ray is directed perpendicular to the image receptor and enters the base of the third metatarsal for an AP axial projection of the foot. This angle allows visualization of the tarsometatarsal joint space without much superimposition of the metatarsals.

When the film is taken front to back, with the back being against the film, it is anteroposterior (AP).
AP means anteroposterior (front to back) so you will see the front of the spine
ap central excise
beam is directed perpendicular to the film centered to the base of the 3rd metatarsals or the beam is angled 10 degrees posteriorly to the base of the 3rd metatarsals
Supine facing the x'ray machine

The CR should enter the patient's ankle joint at the level of the base of the third metatarsal. The central ray should be perpendicular to the long axis of the foot.
The answer is unau (two-toe sloth)
