ARRT POSITIONING || ACKNOWLEDGED ANSWERS
100%.
20° to 25° caudad. correct answers When modifying the PA axial projection of the skull to
demonstrate superior orbital fissures, the central ray is directed
W,I and N correct answers What's accurate positioning or evaluation criteria for an AP projection
of the normal knee?
W. Femorotibial interspaces equal bilaterally.
I. The AP projection of the knee superimposes the patella and femur.
N. The CR should enter at the knee joint, located ½ in. distal to the patellar apex.
25° to 30° caudad correct answers To visualize the rotundum foramina
20° to 25° cephalad correct answers To visualize the inferior orbital fissures
The OML is elevated 15 degrees from the horizontal.
The petrous pyramids projects into the lower third of the orbit.
