Influence on the radiological pathlength

Moving anatomical districts with strong inhomogeneities may cause variation in BP deposition → Particles stop before/beyond the expected position.

→ Uncorrect Dose Distribution

Particle Therapy → high sensitivity of the dose distribution to density variation in the entrance channel → any concept to compensate for the uncertainties due to organ motion/variation needs to incorporate also the influence on the beam’s range on dose DEFORMATION
