what is the correct central ray angulation for the axiolateral projection, coyle method, to demonstrate the coronoid process of the ulna?
30 degrees into the elbow joint toward the shoulder
30 degrees away from the shoulder into the elbow joint
45 degrees away from the shoulder into the elbow joint
45 degrees into the elbow joint toward the shoulder
