Exam-style question
Try this first
Explain how varying photon energy affects the differential absorption of X-rays by different tissues.
Model answer
What a good answer should say
- Different tissues absorb X-rays based on their atomic number and density, which affects how much energy the photons lose.
- Higher energy photons are less likely to be absorbed, allowing them to penetrate denser tissues, resulting in varying image contrast.
Explanation
Why this works
This answer effectively explains the relationship between photon energy and tissue absorption, highlighting the importance of these factors in producing diagnostic images. The question assesses the student's ability to apply knowledge of physics to biological contexts.
