Paul K, Dorsch S, Elter A, Beyer C, Naumann J, Hansmann T, et al.
Phys Med Biol . 2024 Aug; 69(18). PMID: 39191287
Magnetic resonance (MR) images free of artefacts are of pivotal importance for MR-guided ion radiotherapy. This study investigates MR image quality for simultaneous irradiation in an experimental setup using phantom...

Elter A, Dorsch S, Thomas S, Hentschke C, Floca R, Runz A, et al.
Biomed Phys Eng Express . 2021 Jul; 7(5). PMID: 34237712
Polymer gel (PG) dosimetry is a valuable tool to measure complex dose distributions in 3D with a high spatial resolution. However, due to complex protocols that need to be followed...

Elter A, Hellwich E, Dorsch S, Schafer M, Runz A, Kluter S, et al.
Phys Med Biol . 2020 Dec; 66(4):045013. PMID: 33333496
Quality assurance in magnetic resonance (MR)-guided radiotherapy lacks anthropomorphic phantoms that represent tissue-equivalent imaging contrast in both computed tomography (CT) and MR imaging. In this study, we developed phantom materials...

Elter A, Dorsch S, Mann P, Runz A, Johnen W, Spindeldreier C, et al.
Phys Med Biol . 2019 Oct; 64(22):225003. PMID: 31610529
Online adaptive treatment procedures in magnetic resonance (MR)-guided radiotherapy (MRgRT) allow compensating for inter-fractional anatomical variations in the patient. Clinical implementation of these procedures, however, requires specific end-to-end tests to...

Dorsch S, Mann P, Elter A, Runz A, Spindeldreier C, Kluter S, et al.
Phys Med Biol . 2019 Sep; 64(20):205011. PMID: 31530763
For hybrid devices combining magnetic resonance (MR) imaging and a linac for radiation treatment, the isocenter accuracy as well as image distortions have to be checked. This study presents a...

Elter A, Dorsch S, Mann P, Runz A, Johnen W, Karger C
Phys Med Biol . 2019 Jan; 64(4):04NT02. PMID: 30650389
Polymer gel (PG) dosimetry enables three dimensional (3D) measurement of complex dose distributions. However, PGs are strongly reactive with oxygen and other contaminations, limiting their applicability by the need to...

Dorsch S, Mann P, Lang C, Haering P, Runz A, Karger C
Phys Med Biol . 2018 May; 63(11):11NT02. PMID: 29722290
For conventional irradiation devices, the radiation isocenter accuracy is determined by star shot measurements on films. In magnetic resonance (MR)-guided radiotherapy devices, the results of this test may be altered...

Theor Appl Genet . 2003 Aug; 107(7):1278-87. PMID: 12898023
Mildew-resistant mutants were induced with sodium azide in three North American malting barley cultivars, two in the six-rowed Ursula (URS1 and URS2), one in the six-rowed Gertrud (GER1), and one...
