Combined photon-proton modeling of radiation-induced brain imaging changes supports variability in proton relative biological effectiveness and increased periventricular radiosensitivity
Martina Palkowitsch, Larissa S. Kilian, Fabian Hennings +8
Purpose: Recent proton-only investigations of radiation-induced contrast enhancements (RICE) in brain tumor patients indicated variability in proton relative biological effectivene…
An ion-independent phenomenological relative biological effectiveness (RBE) model for proton therapy
Liheng Tian, Christian Hahn, Armin Luehr
Background: A relative biological effectiveness (RBE) of 1.1 is used for proton therapy though clinical evidence of varying RBE was raised. Clinical studies on RBE variability have…
Dosimetric evidence confirms computational model for magnetic field induced dose distortions of therapeutic proton beams
Sonja M Schellhammer, Sebastian Gantz, Armin Lühr +3
Given the sensitivity of proton therapy to anatomical variations, this cancer treatment modality is expected to benefit greatly from integration with magnetic resonance (MR) imagin…
Analytical expressions for stopping-power ratios relevant for accurate dosimetry in particle therapy
Armin Lühr, David C. Hansen, Oliver Jäkel +2
In particle therapy, knowledge of the stopping-power ratios (STPRs) of the ion beam for air and water is necessary for accurate ionization chamber dosimetry. Earlier work has inves…
Full two-electron calculations of antiproton collisions with molecular hydrogen
Armin Lühr, Alejandro Saenz
Total cross sections for single ionization and excitation of molecular hydrogen by antiproton impact are presented over a wide range of impact energy from 1 keV to 6.5 MeV. A nonpe…
Collisions of antiprotons with hydrogen molecular ions
Armin Lühr, Alejandro Saenz
Time-dependent close-coupling calculations of the ionization and excitation cross section for antiproton collisions with molecular hydrogen ions are performed in an impact-energy r…
