Which of the following is the best protective measure for the occupational radiographer to seek protection from scatter radiation?

time
shielding
alternate imaging systems
increase tube filtration

Question 2

In reference to the image, what indicates the part to be properly positioned?

leg was properly internally rotated 15-20 degrees because the lesser trochanter is not visible
leg was properly internally rotated 15-20 degrees because the femoral condyles are parallel to the image receptor
leg was properly internally rotated 5 degrees because the femoral condyles are parallel to the image receptor
leg was properly internally rotated 5 degrees because the lesser trochanter is not visible

Answer to Question 1

shielding

Rationale: Protective shielding devices should be used whenever protective barriers are not available.

Answer to Question 2

leg was properly internally rotated 15-20 degrees because the lesser trochanter is not visible

Rationale: The AP proximal femur will rotate the leg internally 15-20 degrees to place the femoral neck parallel to the image receptor, which will rotate the lesser trochanter to behind the femur. With the AP distal femur, the leg is internally rotated 5 degrees or until the femoral condyles are parallel to the image receptor.
