Exam-style question
Try this first
Explain how the rotation of X-ray sources and detectors in a CT scanner contributes to image formation.
Model answer
What a good answer should say
- The rotation of X-ray sources and detectors allows for the acquisition of multiple images from various angles, which enhances the detail and accuracy of the cross-sectional images.
- This technique reduces the effects of overlapping tissues and improves the contrast of the images.
Explanation
