Mastery checklist
Know what success looks like.
- 01
Connect the underlying interaction to the signal or contrast used to form an image.
- 02
Use the relevant travel-time, attenuation, energy, or resolution relationship.
- 03
Explain one practical limitation or safety trade-off of the technique.
Exam lens
Build, apply, check.
24 Medical physics sits inside A Level extension. Build the concept first, then practise selecting a model, showing working, and checking the final result.
