How do CT scans differ from traditional X-ray imaging in terms of image production?.
- A.CT scans provide 2D images while X-rays provide 3D images
- B.CT scans use a rotating X-ray source while X-rays use a stationary source
- C.CT scans require contrast media while X-rays do not
- D.CT scans are less detailed than traditional X-ray images
Model answer
What a good answer should say
- CT scans use a rotating X-ray source while X-rays use a stationary source
Explanation
Why this works
CT scans employ a rotating X-ray source to capture multiple images from different angles, resulting in detailed cross-sectional images, unlike traditional X-rays which use a stationary source for flat images.
