Journal ArticleDOI
Exploration and application of phenomenological RBE models for proton therapy
Eivind Rørvik,Lars Fredrik Fjæra,Tordis J. Dahle,Jon Espen Dale,G.M. Engeseth,Camilla H. Stokkevåg,S. Thörnqvist,S. Thörnqvist,Kristian S. Ytre-Hauge +8 more
TL;DR: There were considerable variations between the estimations of RBE and RBE-weighted doses from the different models and these variations were a consequence of fundamental differences in experimental databases, model assumptions and regression techniques.
Journal ArticleDOI
A phenomenological biological dose model for proton therapy based on linear energy transfer spectra.
Eivind Rørvik,S. Thörnqvist,S. Thörnqvist,Camilla H. Stokkevåg,Tordis J. Dahle,Lars Fredrik Fjæra,Lars Fredrik Fjæra,Kristian S. Ytre-Hauge +7 more
TL;DR: Analysis indicated that non‐linear models could give a better representation of the RBE‐LET relationship, as differences between the models were observed for the SOBP scenario, and both non‐ linear LET spectrum‐ and linear LETd based models should be further evaluated in clinically realistic scenarios.
Journal ArticleDOI
Monte Carlo simulations of a low energy proton beamline for radiobiological experiments
Tordis J. Dahle,Anne Marit Rykkelid,Camilla H. Stokkevåg,Andrea Mairani,Andreas Görgen,Nina Jeppesen Edin,Eivind Rørvik,Lars Fredrik Fjæra,Eirik Malinen,Eirik Malinen,Kristian S. Ytre-Hauge +10 more
TL;DR: MC simulations accurately modeled the dose distribution from the proton beam and could be used to estimate the LET at any position in the setup, which can beused to study the RBE for protons at high LETd, which is not achievable in clinical proton therapy facilities.
Journal ArticleDOI
Modelling of organ-specific radiation-induced secondary cancer risks following particle therapy.
Camilla H. Stokkevåg,Camilla H. Stokkevåg,Mai Fukahori,Takuma Nomiya,Naruhiro Matsufuji,G.M. Engeseth,Liv Bolstad Hysing,Kristian S. Ytre-Hauge,Eivind Rørvik,Artur Krzysztof Szostak,Ludvig Paul Muren +10 more
TL;DR: Based on the wide spread in RR between patients and variations across the included parameter values, the risk profiles of the rectum and bladder were not dramatically different for the investigated radiotherapy techniques.
Journal ArticleDOI
The FLUKA Monte Carlo code coupled with an OER model for biologically weighted dose calculations in proton therapy of hypoxic tumors.
Tordis J. Dahle,Espen Rusten,Camilla H. Stokkevåg,Antti Silvoniemi,Andrea Mairani,Lars Fredrik Fjæra,Eivind Rørvik,Helge Henjum,Pauliina Wright,Camilla Grindeland Boer,Sarita Forsback,Heikki Minn,Eirik Malinen,Kristian S. Ytre-Hauge +13 more
TL;DR: A Monte Carlo based tool for inclusion of both OER and relative biological effectiveness (RBE) in biologically weighted dose (ROWD) calculations in proton therapy and applied this to explore the impact of hypoxia to create a tool that may be useful in future clinical applications of Hypoxia-guided particle therapy.
