A left lateral lumbar projection with poor positioning demonstrates rotation. The posterior ribs that are most magnified and projected inferiorly are rotated anteriorly. How should the patient be repositioned for an optimal projection to be obtained?

a. Rotate the patient's right side posteriorly.
b. Angle the central ray caudally.
c. Rotate the patient's left side posteriorly.
d. Position the vertebral column parallel with the imaging table.

Question 2

A lateral lumbar projection demonstrates closed L4-5 and L5-S1 intervertebral disk spaces. How should the positioning setup be adjusted for an optimal projection to be obtained?

2. Rotate the patient into a true lateral position.
3. Align the central ray perpendicular to the L5-S1 vertebral column area.
4. Align the vertebral column parallel with the imaging table.
