Monte Carlo Simulation of the Treatment of Uveal Melanoma Using Measured Heterogeneous 106Ru Plaques

Autor: Andrea Wittig, Dirk Flühs, Lorenzo Brualla, Francisco J. Zaragoza, Wolfgang Sauerwein, Marion Eichmann

Publikováno v: Ocular Oncology and Pathology. 5:276-283

Background/Aims: Ruthenium plaques are used for the treatment of ocular tumors. The aim of this work is the comparison between simulated absorbed dose distributions tallied in an anthropomorphic phantom, obtained from ideal homogeneous plaques, and r

Monte Carlo Estimation of Absorbed Dose Distributions Obtained from Heterogeneous 106Ru Eye Plaques

Autor: Dirk Flühs, Francisco J. Zaragoza, Marion Eichmann, Wolfgang Sauerwein, Lorenzo Brualla

Publikováno v: Ocular Oncology and Pathology. 3:204-209

Background: The distribution of the emitter substance in 106Ru eye plaques is usually assumed to be homogeneous for treatment planning purposes. However, this distribution is never homogeneous, and it widely differs from plaque to plaque due to manuf

Energy dependent response of plastic scintillation detectors to photon radiation of low to medium energy

Autor: Melanie Ebenau, Markus Bambynek, Marion Eichmann, B. Spaan, Dirk Flühs, Désirée Radeck, Holger Sommer

Publikováno v: Medical Physics. 43:4598-4606

Purpose: Plastic scintillation detectors are promising candidates for the dosimetry of low- to medium-energy photons but quantitative knowledge of their energy response is a prerequisite for their correct use. The purpose of this study was to charact

Dose Distributions and Treatment Margins in Ocular Brachytherapy with 106Ru Eye Plaques

Autor: Wolfgang Sauerwein, Marion Eichmann, Erik Stöckel, B. Spaan, Dirk Flühs, Norbert Bornfeld, Holger Sommer, Eva Biewald

Brachytherapy with 106Ru eye plaques is the most common treatment modality for small to medium-sized uveal melanomas in Europe. So far, no standardized or widely accepted dose prescription protocol for the irradiation of intraocular tumors with 106Ru

Monte Carlo simulation of ruthenium eye plaques with GEANT4: influence of multiple scattering algorithms, the spectrum and the geometry on depth dose profiles

Autor: Marion Eichmann, B. Spaan, M Ebenau, Holger Sommer

Publikováno v: Physics in medicine and biology. 62(5)

Previous studies show remarkable differences in the simulation of electron depth dose profiles of ruthenium eye plaques. We examined the influence of the scoring and simulation geometry, the source spectrum and the multiple scattering algorithm on th
