Question

question 3/10 where should the central ray be directed for a supine anteroposterior (ap) abdomen radiograph on a sthenic patient? anterior superior iliac spine (asis) iliac crest symphysis pubis lower costal margin

Explanation:

In a supine AP abdomen radiograph of a sthenic patient, the central ray is directed at the iliac crest. This ensures proper visualization of the abdominal contents.

Answer:

B. Iliac crest
