Model answer
What a good answer should say
- Different tissues have varying densities and atomic numbers.
Explanation
Why this works
Different tissues have varying densities and atomic numbers, which affects how they interact with X-rays. The mechanism involves the absorption of X-rays being greater in denser tissues, such as bone, due to their higher atomic number.
This leads to an effect where denser tissues appear lighter on X-ray images, allowing for differentiation between various tissues, which is crucial for accurate diagnosis.
