What is the key difference between spatial resolution and contrast resolution in X-ray imaging?.
- A.Spatial resolution relates to detail, while contrast resolution relates to differences in tissue density.
- B.Spatial resolution is affected by exposure time, while contrast resolution is not.
- C.Spatial resolution is determined by the X-ray source, while contrast resolution is determined by the detector.
- D.Spatial resolution refers to the overall brightness, while contrast resolution refers to the clarity of edges.
Model answer
What a good answer should say
- Spatial resolution relates to detail, while contrast resolution relates to differences in tissue density.
Explanation
Why this works
Spatial resolution refers to the ability to distinguish small details in an image, while contrast resolution pertains to the ability to differentiate between varying tissue densities. Both are essential for high-quality imaging, but they apply to different aspects of image quality.
