Photons p +, C6+
Exponential dose fall off after build up Inverse dose profile with a maximum
energy deposition in the Bragg Peak
→ Steep distal dose fall off (they stop)
Particle Therapy - Rational
1) Superior physical dose deposition properties
→ Dose at depth (target) is greater than
dose at surface.
Reference radiation RBE RBE > 1
2) Higher relative biological effectiveness (RBE)
