Some practical aspect in ion beam planning
For plan creation:
– Limited number of beams should be chosen
– Beam path optimization: Picking “good” beam directions to avoid to
pass through heterogeneities or lie tangent to a tissue air-interface
– Intelligent creation of planning help structures for PTV and targets
– Visualization of spot distribution and weighting
– Avoiding corners and edges from positioning devices/ no beam path
through shoulders
For plan quality assessment:
– Robust evaluation and optimisation
– Surface dose!
– Hot spots within OARs (position of high dose areas)
