kVp & mAs Explained: How to Balance Image Quality and Patient Safety

kVp & mAs are two of the most important exposure factors in radiography — and understanding how to balance them is the key to producing high-quality images while protecting your patient. In this video, we break down kVp (kilovoltage peak) and mAs (milliampere-seconds) in a simple and practical way. You’ll learn how kVp controls beam energy and penetration, how mAs affects image density and noise, and why adjusting one factor often requires changing the other. We’ll also explain: • How kVp influences image contrast • How mAs affects radiation dose • The relationship between exposure factors and image receptor response • The 15% rule and when to apply it • Common mistakes students make when setting exposure parameters Most importantly, you’ll understand how to apply the ALARA principle to maintain diagnostic image quality while minimizing patient radiation exposure. Whether you’re a radiography student or already working in medical imaging, this lesson will help you confidently select exposure factors that achieve the perfect balance between image clarity and patient safety.
