What is the relationship between X-ray absorption and image contrast?.
- A.Higher absorption leads to lower image contrast.
- B.Lower absorption leads to higher image contrast.
- C.Higher absorption leads to higher image contrast.
- D.Absorption does not affect image contrast.
Model answer
What a good answer should say
- Higher absorption leads to higher image contrast.
Explanation
Why this works
Higher absorption refers to the ability of tissues to absorb X-rays more effectively, resulting in greater differences in X-ray intensity on the image. This contrast is crucial for distinguishing between different tissues and structures in the image, making it easier to identify abnormalities.
