PET scanning is mapped to 24 Medical physics in the Cambridge International AS & A Level Physics pathway. Use this public guide to see exactly where the concept fits, what to master, and which GioPhysics resource continues the study sequence.
Where this fits
24 Medical physics
- Curriculum
- Cambridge International AS & A Level Physics
- Theme or group
- A Level extension
- Current framework
- Examinations in 2025–2027 · Version 1
X-ray production and attenuation, CT, ultrasound with acoustic impedance, and PET follow the 9702 outline.
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.
