• The experimental dose ranges influence the LET_d dependency of the proton minimum RBE (RBE_min) 

      Rørvik, Eivind; Thørnqvist, Sara; Ytre-Hauge, Kristian (Peer reviewed; Journal article, 2019-09-23)
      Cell experiments have shown the proton relative biological effectiveness (RBE) to vary with dose and linear energy transfer (LET), which has led to development of variable RBE models. The RBE is normally estimated from two ...
    • Helium radiography with a digital tracking calorimeter—a Monte Carlo study for secondary track rejection 

      Pettersen, Helge Egil Seime; Volz, Lennart; Sølie, Jarle Rambo; Alme, Johan; Barnaföldi, Gergely Gábor; Barthel, Rene; van den Brink, Anthony; Borshchov, Vyacheslav; Chaar, Mamdouh; Eikeland, Viljar Nilsen; Genov, Georgi; Grøttvik, Ola Slettevoll; Helstrup, Håvard; Keidel, Ralf; Kobdaj, Chinorat; van der Kolk, Naomi; Mehendale, Shruti Vineet; Meric, Ilker; Odland, Odd Harald; Papp, Gábor; Peitzmann, Thomas; Piersimoni, Pierluigi; Protsenko, Maksym; Rehman, Attiq Ur; Richter, Matthias; Samnøy, Andreas Tefre; Seco, Joao; Shafiee, Hesam; Songmoolnak, Arnon; Tambave, Ganesh Jagannath; Tymchuk, Ihor; Ullaland, Kjetil; Varga-Kofarago, Monika; Wagner, Boris; Xiao, Renzheng; Yang, Shiming; Yokoyama, Hiroki; Röhrich, Dieter Rudolf Christian (Journal article; Peer reviewed, 2021)
      Radiation therapy using protons and heavier ions is a fast-growing therapeutic option for cancer patients. A clinical system for particle imaging in particle therapy would enable online patient position verification, ...
    • Image quality of list-mode proton imaging without front trackers 

      Sølie, Jarle Rambo; Volz, Lennart; Pettersen, Helge Egil Seime; Piersimoni, Pierluigi; Odland, Odd Harald; Røhrich, Dieter; Helstrup, Håvard; Peitzmann, Thomas; Ullaland, Kjetil; Varga-Kofarago, Monika; Mehendale, Shruti Vineet; Grøttvik, Ola Slettevoll; Eikeland, Viljar Nilsen; Meric, Ilker; Seco, Joao (Journal article; Peer reviewed, 2020)
      List mode proton imaging relies on accurate reconstruction of the proton most likely path (MLP) through the patient. This typically requires two sets of position sensitive detector systems, one upstream (front) and one ...
    • Implementation of a double scattering nozzle for Monte Carlo recalculation of proton plans with variable relative biological effectiveness 

      Fjæra, Lars Fredrik; Indelicato, Daniel J.; Stokkevåg, Camilla Hanquist; Muren, Ludvig Paul; Hsi, Wen C.; Ytre-Hauge, Kristian (Journal article; Peer reviewed, 2020)
      A constant relative biological effectiveness (RBE) of 1.1 is currently used in clinical proton therapy. However, the RBE varies with factors such as dose level, linear energy transfer (LET) and tissue type. Multiple RBE ...
