A hybrid multi-particle approach to range assessment-based treatment verification in particle therapy
Meric, Ilker; Alagoz, Enver; Hysing, Liv Bolstad; Kögler, Toni; Lathouwers, Danny; Lionheart, William R. B.; Mattingly, John; Obhodas, Jasmina; Pausch, Guntram; Pettersen, Helge Egil Seime; Ratliff, Hunter Nathaniel; Rovituso, Marta; Schellhammer, Sonja M.; Setterdahl, Lena Marie; Skjerdal, Kyrre; Sterpin, Edmond; Sudac, Davorin; Turko, Joseph A.; Ytre-Hauge, Kristian Smeland (Journal article; Peer reviewed, 2023)Particle therapy (PT) used for cancer treatment can spare healthy tissue and reduce treatment toxicity. However, full exploitation of the dosimetric advantages of PT is not yet possible due to range uncertainties, warranting ... -
Improving knowledge-based treatment planning for lung cancer radiotherapy with automatic multi-criteria optimized training plans
Fjellanger, Kristine; Hordnes, Marte; Sandvik, Inger Marie; Sulen, Turid Husevåg; Heijmen, Ben J. M.; Breedveld, Sebastiaan; Rossi, Linda; Pettersen, Helge Egil Seime; Hysing, Liv Bolstad (Journal article; Peer reviewed, 2023)Background: Knowledge-based planning (KBP) is a method for automated radiotherapy treatment planning where appropriate optimization objectives for new patients are predicted based on a library of training plans. KBP can ... -
Influence of organ motion on conformal vs. intensity-modulated pelvic radiotherapy for prostate cancer
Hysing, Liv Bolstad; Skorpen, Tone Nybø; Alber, Markus; Fjellsbø, Lise Bauge; Helle, Svein Inge; Muren, Ludvig Paul (Peer reviewed; Journal article, 2008-08-01) -
Intensity-modulated radiotherapy of pelvic lymph nodes in locally advanced prostate cancer: planning procedures and early experiences

Mixed Effect Modeling of Dose and Linear Energy Transfer Correlations With Brain Image Changes After Intensity Modulated Proton Therapy for Skull Base Head and Neck Cancer
Engeseth, Grete May; He, Renjie; Mirkovic, Dragan; Yepes, Pablo; Mohamed, Abdallah Sherif Radwan; Stieb, Sonja; Fuller, Clifton Dave; Wu, Richard; Zhang, Xiadong; Hysing, Liv Bolstad; Pettersen, Helge Egil Seime; Stokkevåg, Camilla Hanquist; Mohan, Radhe; Frank, Steven Jay; Gunn, Gary Brandon (Journal article; Peer reviewed, 2021)Purpose Intensity modulated proton therapy (IMPT) could yield high linear energy transfer (LET) in critical structures and increased biological effect. For head and neck cancers at the skull base this could potentially ... -
An organ deformation model using Bayesian inference to combine population and patient-specific data
Rørtveit, Øyvind Lunde; Hysing, Liv Bolstad; Stordal, Andreas Størksen; Pilskog, Sara Margareta Cecilia (Journal article; Peer reviewed, 2023)Objective. Organ deformation models have the potential to improve delivery and reduce toxicity of radiotherapy, but existing data-driven motion models are based on either patient-specific or population data. We propose to ... -
Patient selection, inter-fraction plan robustness and reduction of toxicity risk with deep inspiration breath hold in intensity-modulated radiotherapy of locally advanced non-small cell lung cancer
Fjellanger, Kristine; Rossi, Linda; Heijmen, Ben J.M.; Pettersen, Helge Egil Seime; Sandvik, Inger Marie; Breedveld, Sebastiaan; Sulen, Turid Husevåg; Hysing, Liv Bolstad (Journal article; Peer reviewed, 2022)Background: State-of-the-art radiotherapy of locally advanced non-small cell lung cancer (LA-NSCLC) is performed with intensity-modulation during free breathing (FB). Previous studies have found encouraging geometric ... -

Reducing systematic errors due to deformation of organs at risk in radiotherapy
Rørtveit, Øyvind Lunde; Hysing, Liv Bolstad; Stordal, Andreas Størksen; Pilskog, Sara Margareta Cecilia (Journal article; Peer reviewed, 2021)Purpose In radiotherapy (RT), the planning CT (pCT) is commonly used to plan the full RT-course. Due to organ deformation and motion, the organ shapes seen at the pCT will not be identical to their shapes during RT. Any ... -
