abstract = {The physical and biological properties of ion-beams offer
various advantages in comparison to conventional
radiotherapy, though uncertainties concerning quality
assurance are still left. Due to the inverted depth dose
profile, range accuracy is of paramount importance. We
investigated the range deviations between planning
simulation and post-fractional PET/CT measurement from
particle therapy in primary glioblastoma.20 patients with
glioblastoma undergoing particle therapy at our institution
were selected. 10 received a proton-boost, 10 a
carbon-ion-boost in addition to standard treatment. After
two fractions, we performed a PET/CT-scan of the brain. We
compared the resulting range deviation based on the
Most-likely-shift method between the two measurements, and
the measurements with corresponding expectations, calculated
with the Monte-Carlo code FLUKA.A patient's two measurements
deviated by 0.7mm (±0.7mm). Overall comparison between
measurements and simulation resulted in a mean range
deviation of 3.3mm (±2.2mm) with significant lower
deviations in the (12)C-arm.The used planning concepts
display the actual dose distributions adequately. The carbon
ion group's results are below the used PTV safety margins
(3mm). Further adjustments to the simulation are required
for proton irradiations. Some anatomical situations require
particular attention to ensure highest accuracy and safety.},
