3. Define spatial resolution. 4. How is the CT image affected by too low an mAs setting?

How is it affected if the mAs setting is too high? 5. Give examples of examinations in which images may need to be reconstructed twice, using different algorithms. 6. How does a change in slice thickness affect the spatial resolution? How does it affect contrast resolution? What effect

will it have on patient dose?
