- A.To enhance the imaging quality
- B.To focus the radiation on the tumor site
- C.To increase the radiation dose
- D.To decrease the treatment time
Model answer
What a good answer should say
- To focus the radiation on the tumor site
Explanation
Why this works
The primary reason for shaping high-energy X-ray beams is to focus the radiation on the tumor site. This mechanism allows for a concentrated dose of radiation to be delivered directly to the tumor, maximizing treatment efficacy while minimizing exposure to surrounding healthy tissue, which is essential for reducing side effects.
