During a PA axial projection of the skull using the Caldwell method, which two anatomic structures will be in contact with the image receptor? (Select two)

In a PA axial projection of the skull using the Caldwell method, the evaluated positioning aims to demonstrate the orbits and frontal bone clearly. The appropriate anatomical structures that come into contact with the image receptor during this projection are crucial for alignment and obtaining a quality radiographic image.

When the Caldwell method is performed, the patient’s forehead and nose make contact with the image receptor. This positioning ensures that the central ray is directed along the orbitomeatal line, typically angled at 15 degrees caudal, to adequately visualize the frontal sinuses and the occipital region. By positioning the forehead and nose against the receptor, the radiographer can achieve proper alignment that facilitates the required angling of the beam.

The other options do not reflect the standard positioning necessary for this specific projection, highlighting the importance of the selected structures in achieving the desired imaging results for cranial anatomy.
