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
