PA Axial Caldwell: what was the error? 5..png 

A poorly positioned PA Axial Caldwell, cranial projection demonstrates the petrous ridges inferior to the infraorbital margins. What was the error? Select all that applies. 1. Patient’s was tucked too low 2. CR was insufficiently angled 3. CR was excessively angled 4. Patient’s chin was too high

A PA Skull projection with accurate positioning demonstrates: 1. equal distances from lateral orbital margin to lateral borders of the skull on both sides 2. the frontal bone of interest 3. the petrous ridges horizontally through the lower third of the orbits 4. demonstrate maxillary sinuses without superimposition of petrous ridges

A PA skull was performed showing the Petrous Ridges at the inferior 1/3 border of the orbits. How should the error in question above, be corrected?
