How is the red plot created in proton therapy?
How is the red plot created in proton therapy?
- By replacing the blue Bragg peak with a red one
- By adding different energy Bragg peaks to the blue one (correct)
- By increasing the energy of the proton beam
- By reducing the thickness of the prospect pieces
What technique is used to create Bragg peaks with reduced energy?
What technique is used to create Bragg peaks with reduced energy?
- Inserting more prospect pieces
- Active beam delivery with scattering foils
- Passive scattering with a range modulator wheel (correct)
- Using 2 magnets to scan the beam
What is the purpose of the prospect pieces in the range modulator wheel?
What is the purpose of the prospect pieces in the range modulator wheel?
- To increase the energy of the proton beam
