PA Skull X Ray
By placing the forehead against the image detector, the PA skull view is of the entire skull and is non angled. It does not highlight any particular area.
The name PA is because the x ray beam travels Posterior to Anterior through the skull.
The PA Skull View has a lower radiation dose to the eyes than the AP view, and it has less magnification of the bones. But the inherent overlap of the bone structures are not optimal for diagnosing dental conditions impacting the sinuses. The CBCT TMJ Slices imaging is ideal for evaluating airways.
