What is the effect of mAs in x-ray?

Answer 1

The milliampere-seconds (mAs) in x-ray imaging controls the quantity of x-ray photons produced during an exposure. Increasing the mAs results in more photons, which enhances image brightness and contrast, making structures easier to visualize. However, higher mAs also increases patient radiation dose, so it’s essential to optimize mAs to balance image quality and patient safety. Proper adjustment of mAs is crucial in achieving diagnostic-quality images while minimizing radiation exposure.
