Which magnification factor would result in the greatest amount of size distortion present on an image?

• A. 1.18
• B. 2.04
• C. 1.32
• D. 2.56

Answer: (D)

Size distortion scrolls up as the object is magnified more by the X-ray beam. The magnification factor tells us how much larger the image is than the actual object; the bigger that factor, the more enlargement and thus more distortion we see. So, among the options, the one with the greatest magnification factor would produce the most distortion. In practical terms, increasing SID relative to SOD increases the magnification factor, leading to more enlargement, while keeping alignment and geometry proper helps minimize distortion.
