Why are high-energy X-ray beams shaped and targeted during treatment?.
- A.To minimize damage to surrounding healthy tissue
- B.To increase the intensity of the radiation
- C.To reduce the cost of treatment
- D.To ensure a longer treatment duration
Model answer
What a good answer should say
- To minimize damage to surrounding healthy tissue
Explanation
Why this works
Shaping and targeting high-energy X-ray beams minimizes damage to surrounding healthy tissue. This is crucial because while the beams effectively destroy tumor cells, the mechanism of precise targeting ensures that the radiation primarily affects the tumor, reducing collateral damage to healthy cells and thus improving patient outcomes.
