| Question | Answer |
| The parietoacanthial projection requires the CR to exit the: | acanthion |
| The best single projection for facial bones is: | parietoacanthial (Water) |
| What baseline is placed parallel to the transverse axis of the IR for a lateral projection of the facial bones? | infraorbitomeatal |
| For the Waters method, the orbilomeatal line is placed at what angle to the IR? | 37 degrees |
| The parietoacanthiomeatal of the facial bones is often modified so there is less angulation of the facial bones, the sorbitomeatal line is adjusted to what angle? | 55 degrees |
| What baseline is placed perpendicular to the IR for the acanthioparietal projection of the facial bones? | mentomeatal line |
| The CR angulation for the Waters method is: | 0 |
| Which facial bones are clearly demonstrated in the parietoacanthial (Waters) projection? | orbits, maxillae, zygomatic arches |
| For a lateral projection of the facial bones the CR will enter the: | halfway between the outer canthus and the EAM |
| The best projection for orbital fractures is the: | Modified Waters |
| Trauma patents may arrive in the department with their ahead mobolized, a reverse watersd can be performed by adjusting the CR to be parallel to the: | mentomeatal line |
| To correct positioning for a situation where the petrous pyramids are projected in the maxillary sinuses for a parietoacanthial projection a technologist should: | extend the chin |
| In the parietoacanthial projection, the orbital floor should be: | perpendicular to the IR and parallel to the CR |
| For a lateral projection of the facial bones, the IR is centered to the: | zygomatic bone |
| Where is the CR for the parietoacanthial projection of the facial bones? | acanthion |
| The lateral projection clearly demonstrates the: | all facial bones in their entirety |
