What is the dose area product (DAP) if the collimated field is 10 X
10 cm with a dose of 2 roentgens/minute (R/min)?
A. 100 R per cm squared.
b. 20 R per cm squared.
C. 200 R per cm squared.
D. 10 R per cm squared. - ✔✔✔ correct answer > b. 20 R per cm
squared.
DAP considers not only the dose, but also the volume of tissue
irradiated. To arrive at the correct answer, the volume of tissue
radiated (100 cm2) is multiplied by the dose received (2 R/min).
A lateral L-5/S-1 lumbosacral junction is performed with the
central ray (CR) directed 2 inches anterior to the anterior
superior iliac spine (ASIS) and 1-1/2 inches inferior to the iliac
crest. Which statement describes this method?
,Page 2 of 106
A. The central ray will be well posterior to the L-5/S-1 junction.
B. The central ray will be well anterior to the L-5/S-1 junction.
C. The central ray will be correctly centered to the L-5/S-1
junction.
D.The central ray will be well superior to the L-5/S-1 junction. -
✔✔✔ correct answer > B. The central ray will be well anterior to the L-
5/S-1 junction.
To demonstrate the L-5/S-1 lumbosacral junction, the central ray
(CR) is directed 2 inches posterior to the anterior superior iliac
spine (ASIS) and 1-1/2 inches inferior to the iliac crest.
Which projection best demonstrates the aortic impression on the
esophagus in an esophagram?
A. Left lateral
B. RAO
C. LAO
D. PA - ✔✔✔ correct answer > B. RAO
,Page 3 of 106
The best view of the aortic impression on the esophagus is
obtained in the RAO projection. This impression is hidden from
view in the LAO, PA, and left lateral.
Which patient body habitus may require the patient to be in the
Trendelenburg position during a small bowel series?
A. Hyposthenic
B. Asthenic
C. Sthenic
D. Hypersthenic - ✔✔✔ correct answer > B. Asthenic
Asthenic patients may be placed in Trendelenburg position to
separate overlapping loops of small bowel.
Which joint is the central ray (CR) entrance point for a
posteroanterior (PA) finger projection?
A. PIP
B. CMC
C. MCP
D. IP - ✔✔✔ correct answer > A. PIP

Where is the central ray (CR) directed for an anteroposterior
(AP) projection of the lower leg?
A. 2 inches distal to the medical condyle of the tibia
B. Mid-lower leg
C. At the level of the medial malleolus
D. 0.5 inch inferior to the patellar apex - ✔✔✔ correct answer > B. Mid-
lower leg
Which central ray (CR) angle is best for heavy, wide-hipped
patients for lateral lumbar spine projections?
A. 5 degrees cephalad
B. Perpendicular
C. 10 degrees caudad
D. 5 degrees caudad - ✔✔✔ correct answer > D. 5 degrees caudad
With heavy, wide hipped patients, it is best to begin with a 5
degree caudal angle. Perpendicular CRs simply don't work well
with these patients. Extreme cases of wide hips may require
even more angle of 10 degrees caudad, but these will be the true
exception, rather than the rule. A cephalic angle would close the
joint spaces.
