Impact of new ICRU90 key data on stopping-power ratios and beam quality correction factors for carbon ion beams
Lucas Burigo, Steffen Greilich
The recent update of dosimetric key data by the `International Commission on Radiation Units and Measurements' impacts the computation of beam quality correction factors via…
Experimental verification of stopping-power prediction from single- and dual-energy computed tomography in biological tissues
Christian Möhler, Tom Russ, Patrick Wohlfahrt +4
An experimental setup for consecutive measurement of ion and x-ray absorption in tissue or other materials is introduced. With this setup using a 3D-printed sample container, the r…
Assessment of Microscopic Ion Beam Field Variation using Fluorescent Nuclear Track Detectors
Alexander Neuholz, Steffen Greilich
Fluorescent Nuclear Track Detectors (FNTDs) offer a superior, sub-micrometer spatial resolution that allows for single particle track detection. However, when assessing particle fl…
Measurement of fluence, LET, and dose in a carbon ion spread-out Bragg-peak using fluorescent nuclear track detectors and an automated reader
Steffen Greilich, Leonie Ulrich, Jasper J. M. Kouwenberg +1
For the assessment of radiation effects of clinical ion-beams, dosimetry has to be complemented by information on particle-energy distribution or related quantities. Fluorescence n…
Range prediction for tissue mixtures based on dual-energy CT
Christian Möhler, Patrick Wohlfahrt, Christian Richter +1
The use of dual-energy CT (DECT) potentially decreases range uncertainties in proton and ion therapy treatment planning via determination of the involved physical target quantities…
Methodological accuracy of image-based electron-density assessment using dual-energy computed tomography
Christian Möhler, Patrick Wohlfahrt, Christian Richter +1
Purpose: Electron density is the most important tissue property influencing photon and ion dose distributions in radiotherapy patients. Dual-energy computed tomography (DECT) enabl…
An anthropomorphic multimodality (CT/MRI) phantom prototype for end-to-end tests in radiation therapy
Raya R. Gallas, Nora Hünemohr, Armin Runz +3
With the increasing complexity of external beam therapy, so-called "end-to-end" tests are intended to cover all steps from therapy planning to follow-up to fulfill the high demands…
Single track coincidence measurements of fluorescent and plastic nuclear track detectors in therapeutic carbon beams
J. -M. Osinga, I. Ambrožová, K. Pachnerová Brabcová +4
In this paper we present a method for single track coincidence measurements using two different track detector materials. We employed plastic and fluorescent nuclear track detector…
Ion track reconstruction in 3D using alumina-based fluorescent nuclear track detectors
Martin Niklas, James A. Bartz, Mark S. Akselrod +3
Fluorescent nuclear track detectors (FNTDs) based on Al2O3:C,Mg single crystal combined with confocal microscopy provide 3D information on ion tracks with a resolution only limited…
Efficient calculation of local dose distribution for response modelling in proton and ion beams
S. Greilich, U. Hahn, M. Kiderlen +2
We present an algorithm for fast and accurate computation of the local dose distribution in MeV beams of protons, carbon ions or other heavy-charged particles. It uses compound Poi…
Absorbed Dose in Ion Beams: Comparison of Ionisation and Fluence-based Measurements
Julia-Maria Osinga, Stephan Brons, James A. Bartz +3
A direct comparison measurement of fluorescent nuclear track detectors (FNTDs) and a thimble ionisation chamber is presented. Irradiations were performed using monoenergetic proton…
