Course book Advanced Treatment Planning 2018

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)
