Question

You are about to take an X-ray of the AP femur. You should place the thicker part of the femur (proximal femur) at which end of the tube in order to get a uniform contrast throughout the radiograph?

Answer 1

The thicker part of the femur (proximal femur) should be placed closer to the anode end of the X-ray tube in order to get a uniform contrast throughout the radiograph. This is because the anode end of the tube produces a sharper image with higher contrast than the cathode end, which produces a softer image with lower contrast. Placing the thicker part of the femur closer to the anode end of the tube will ensure that the image is sharp and well-contrasted throughout.
