Question

The visibility of anatomical detail in a CT image will increase when:

• A. The field of view is increased.
• B. The matrix size is decreased.
• C. The smoothing filter algorithm is used.
• D. The slice thickness is decreased.

Hint:

In CT imaging, thinner slices improve detail resolution, so reducing slice thickness enhances visibility of anatomical structures.

Answer 1

The Correct Option is D

- Decreasing the slice thickness in CT imaging increases the resolution and visibility of fine anatomical details because thinner slices provide higher detail and sharper images.
- Increasing the field of view or decreasing the matrix size would generally reduce the resolution.
- Smoothing filters are used to reduce noise but may blur fine details, not enhance visibility.

Conclusion: Decreasing the slice thickness enhances the visibility of anatomical details, making option (d) correct.
