Journal ArticleDOI
Single Arc Volumetric Modulated Arc Therapy of head and neck cancer.
TL;DR: The VMAT algorithm in Pinnacle generated single arc VMAT plans with equivalent or better target coverage and sparing of OARs compared to IMRT, while both delivery time and MUs were decreased.
Journal ArticleDOI
Automatic planning of head and neck treatment plans.
Irene Hazell,Karl Bzdusek,Prashant Kumar,Christian Rønn Hansen,Anders Bertelsen,Jesper Grau Eriksen,Jesper Grau Eriksen,Jørgen Johansen,Jørgen Johansen,Carsten Brink,Carsten Brink +10 more
TL;DR: The main benefit of the Auto‐Planning method is the likely improvement in the overall treatment quality since consistent, high‐quality plans are generated which even can be further optimized, if necessary.
Journal ArticleDOI
Automatic treatment planning improves the clinical quality of head and neck cancer treatment plans
Christian Rønn Hansen,Anders Bertelsen,Irene Hazell,Ruta Zukauskaite,Ruta Zukauskaite,Niels Gyldenkerne,Jørgen Johansen,Jørgen Johansen,Jesper Grau Eriksen,Jesper Grau Eriksen,Carsten Brink,Carsten Brink +11 more
TL;DR: Autoplan can produce clinically better VMAT radiotherapy plans for H&N cancer with significant sparing of OAR with a template the TPS can automatically create better plans than manually created plans.
Journal ArticleDOI
What is plan quality in radiotherapy? The importance of evaluating dose metrics, complexity, and robustness of treatment plans.
Victor Hernandez,Christian Rønn Hansen,L. Widesott,Anna Bäck,R. Canters,Marco Fusella,J. Götstedt,Diego Jurado-Bruggeman,Nobutaka Mukumoto,L.P. Kaplan,Irena Koniarová,Tomasz Piotrowski,Lorenzo Placidi,Ana Vaniqui,Nuria Jornet +14 more
TL;DR: Better tools are needed in TPSs for the evaluation of dose distributions, for the robust evaluation and optimisation of treatment plans, and for controlling and reporting plan complexity.
Journal ArticleDOI
Osteoradionecrosis of the mandible after radiotherapy for head and neck cancer: risk factors and dose-volume correlations.
S. Aarup-Kristensen,S. Aarup-Kristensen,Christian Rønn Hansen,Christian Rønn Hansen,L. Forner,Carsten Brink,Carsten Brink,Jesper Grau Eriksen,Jørgen Johansen,Jørgen Johansen +9 more
TL;DR: The onset of ORN of the mandible was early (median 10.8 months) and the incidence low (4.6%) after IMRT in HNC cancer patients and smoking only retained its significance in an interaction analysis with pre-RT dental procedures.
