• Hydrocephalic

Which specific positioning error is present if the mandibular rami are not superimposed on a lateral skull projection?

• Rotation

• Incorrect angulation

• Tilt

• Overflexion

What positioning error is shown in the image:

• Tilt

• Rotation

• Excessive angulation

• Hyper-extension

What is the positioning error shown in the image:

• Tilt

• Rotation

• Excessive angulation

• Hyper-extension

You are performing a PA Axial projection of the orbits. What is required to place the petrous portion below the inferior margins of the orbits?

• X-ray beam is perpendicular

• Angle the x-ray beam 15 caudad

• Angle the x-ray beam 30 caudad

• Angle the x-ray beam 37 caudad

What anatomical structure is of primary interest?

• Ethmoid sinus

• Maxillary sinus

• Sphenoid sinus

• Nasal bones

What anatomical structures are best demonstrated in the image:

• TM Joints

• Mandibular condyles

• Ethmoid sinus

• Zygomatic arches

Which 2 bones make up the nasal septum?

• Nasal bones and vomer

• Vomer and ethmoid bone

• Palatine and ethmoid bone

• Maxilla and inferior nasal conchae

The lambdoid suture is located:

• Between the 2 parietal bones

• Between the parietal and occipital bone

• Between the parietal and temporal bones

• Between the parietal and frontal bone

When performing the Towne’s method the patient is unable to flex their neck to place the OML perpendicular to the IR. What can you do to ensure you receive an optimal image?

• IOML perpendicular to the IR and increase angulation to 37 degrees

• OML perpendicular to the IR and increase angulation to 37 degrees

• IOML perpendicular to the IR and decrease angulation to 15 degrees

• MML perpendicular to the IR and use a perpendicular
