What role does tissue density play in X-ray absorption?.
- A.Higher density tissues absorb more X-rays.
- B.Density has no impact on X-ray absorption.
- C.Lower density tissues absorb more X-rays.
- D.All tissues absorb X-rays at the same rate.
Model answer
What a good answer should say
- Higher density tissues absorb more X-rays.
Explanation
Why this works
Higher density tissues absorb more X-rays due to the mechanism of increased mass per unit volume, which leads to more interactions with X-ray photons. The effect is that these tissues appear more opaque on X-ray images, allowing for better visualization of structures, which is vital for accurate diagnostics.
