A Fronto Occipital

The document contains 16 multiple choice questions about radiographic projections and techniques. The questions cover topics like the best projections to demonstrate orbits or the longitudinal arch of the foot, positioning for cervical spine or sella turcica radiographs, tube angles for temporomandibular joint projections, functions of components in an x-ray tube like the focusing cup or oil, and which ribs are best visualized on a PA chest x-ray in full inspiration.
