Routine projections of the orbits include what? | Waters, Caldwell, Lateral |
How many degrees is the head rotated for the parieto-orbital oblique (Rhese) projection of the optic canal? | 53 degrees |
Which line is placed perpendicular to the IR for the parieto-orbital oblique (Rhese) projection of the optic canal? | acanthiomeatal line |
The optic foramen should be seen where in the orbit of a properly positioned parieto-orbital oblique (Rhese) projection? | lower and outer portion of the orbit |
How would you correct positioning in the parieto-orbital oblique (Rhese)projection if the optic foramen is visualized medially in the orbit? | rotate the head laterally (toward the affected orbit) |
To correct for positioning errors when the optic foramen is visualized in the superior portion of the orbit in a parieto-orbital oblique (Rhese) projection you would: | extend the chin |
What bone is not part of the orbit? | parietal |
The CR is positioned where on the parieto-orbital oblique projection? | 1 inch superior to the TEA |
