Journal ArticleDOI
Inclusion of geometrical uncertainties in radiotherapy treatment planning by means of coverage probability
TL;DR: A method has been developed for calculation of CTV-to-PTV margin size based on the assumption that the CTV should be adequately irradiated with a high probability, demonstrated to be fast and accurate for a prostate, cervix, and lung cancer case.
Journal ArticleDOI
Adaptive radiotherapy: The Elekta Unity MR-linac concept.
Dennis Winkel,Gijsbert H. Bol,Petra S. Kroon,Bram van Asselen,Sara S. Hackett,Anita M. Werensteijn-Honingh,Martijn Intven,Wietse S.C. Eppinga,Rob H N Tijssen,Linda G W Kerkmeijer,Hans C.J. de Boer,Stella Mook,Gert J. Meijer,J. Hes,Mirjam Willemsen-Bosman,Eline N. de Groot-van Breugel,Ina M. Jürgenliemk-Schulz,Bas W. Raaymakers +17 more
TL;DR: The Elekta Unity MR-linac adaptive radiotherapy concept is explained and different methods for dose re-calculation and optimization are discussed, with full online re-planning being the most robust adaptive planning method for the Unity.
Journal ArticleDOI
A protocol for the reduction of systematic patient setup errors with minimal portal imaging workload
TL;DR: Application of the NAL protocol to measured setup errors confirmed its efficacy in systematic error reduction in a real patient population, if dedicated large fields are required for portal imaging (double exposure).
Journal ArticleDOI
Internal organ motion in prostate cancer patients treated in prone and supine treatment position.
Joep Stroom,Peter C.M. Koper,Gert A. Korevaaar,Marjolein J.H. van Os,Marjolein Janssen,Hans C.J. de Boer,Peter C. Levendag,Ben J.M. Heijmen +7 more
TL;DR: Compared to patients in supine position, patients in prone position had smaller random but somewhat larger systematic variations in the most important coordinates of the internal CTV position, and the required planning margin is equal for both groups.
Journal ArticleDOI
Reduction of respiratory liver tumor motion by abdominal compression in stereotactic body frame, analyzed by tracking fiducial markers implanted in liver.
Wouter Wunderink,Alejandra Méndez Romero,Willy de Kruijf,Hans C.J. de Boer,Peter C. Levendag,Ben J.M. Heijmen +5 more
TL;DR: Abdominal compression effectively reduced liver tumor motion, yielding small and reproducible excursions in three dimensions, and the compression level established at planning could have been safely used on the treatment days.
