METHODS: Daily kV-control-CTs of six head and neck patients (=175 CTs) were analysed. All volumes of interest were re-contoured using deformable image registration. Three IGRT correction strategies were simulated and the resulting dose distributions were computed for all fractions. Different sets of criteria with varying dose thresholds for re-planning were investigated. All sets of criteria ensure equivalent target coverage of both CTVs, but vary in the tolerance threshold of the spinal cord. RESULTS: The variations of the D95 and D2 in respect to the planned values ranged from -7% to +3% for both CTVs, and -2% to +6% for the spinal cord. Despite different correction vectors of the three IGRT strategies, the dosimetric differences were small. The number of fractions not requiring re-planning varied between 0% and 11% dependent on the applied IGRT correction strategy. In contrast, this number ranged between 32% and 70% dependent on the dosimetric thresholds, even though these thresholds were only gently modified. CONCLUSIONS: The more precise the planned dose needs to be maintained over the treatment course, the more frequently re-planning is required. The influence of different IGRT correction strategies, even though geometrically notable, was found to be of only limited relevance for the re-planning frequency. In contrast, the definition and modification of thresholds for re-planning have a major impact on the re-planning frequency.","is_dataset_classified":null,"base_score":2.833213344056216,"endowment":2.833213344056216,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"25112458","pmcid":"PMC4251689","openalex_id":"https://openalex.org/W2148739118","authors":[],"funders":[{"funder_name":"Deutsche Forschungsgemeinschaft","grant_id":"211469636/TRR 125","title":"Cognition-Guided Surgery"}],"total_grants":1,"fwci":2.3987,"citation_percentile":0.88580903,"influential_citations":0,"citation_trend":[{"year":2015,"count":3},{"year":2016,"count":1},{"year":2017,"count":3},{"year":2018,"count":3},{"year":2020,"count":2},{"year":2021,"count":1},{"year":2023,"count":1},{"year":2024,"count":2}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://ro-journal.biomedcentral.com/counter/pdf/10.1186/1748-717X-9-175","host_type":"journal"},{"url":"https://ro-journal.biomedcentral.com/counter/pdf/10.1186/1748-717X-9-175","host_type":"publisher"},{"url":"http://link.springer.com/content/pdf/10.1186/1748-717X-9-175.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1186/1748-717x-9-175","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/25112458","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/4251689","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC4251689","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC4251689?pdf=render","host_type":"Europe_PMC"},{"url":"https://ro-journal.biomedcentral.com/track/pdf/10.1186/1748-717X-9-175","host_type":""},{"url":"http://dx.doi.org/10.1186/1748-717X-9-175","host_type":""},{"url":"http://dx.doi.org/10.1186/1748-717x-9-175","host_type":""},{"url":"https://dx.doi.org/10.1186/1748-717x-9-175","host_type":""}],"fields_of_study":["Advanced Radiotherapy Techniques","Radiation Dose and Imaging","Head and Neck Cancer Studies","03 medical and health sciences","0302 clinical medicine","Computer Simulation","Decision Making","Head and Neck Neoplasms","Humans","Image Interpretation, Computer-Assisted","Radiotherapy Dosage","Radiotherapy Planning, Computer-Assisted","Radiotherapy, Image-Guided","Radiotherapy, Intensity-Modulated","Tomography, X-Ray Computed","Tumor Burden"],"mesh_terms":["Computer Simulation","Decision Making","Head and Neck Neoplasms","Humans","Image Interpretation, Computer-Assisted","Radiotherapy Dosage","Radiotherapy Planning, Computer-Assisted","Tomography, X-Ray Computed","Tumor Burden","Radiotherapy, Intensity-Modulated","Radiotherapy, Image-Guided"],"keywords":["Medicine","Image-guided radiation therapy","Radiation treatment planning","Head and neck cancer","Medical physics","Head and neck","Radiation therapy","Radiology","Surgery","Research","Radiotherapy Planning, Computer-Assisted","Decision Making","Radiotherapy Dosage","Tumor Burden","Oncology","Radiology Nuclear Medicine and imaging","Head and Neck Neoplasms","Image Interpretation, Computer-Assisted","Humans","Computer Simulation","Radiotherapy, Intensity-Modulated","Tomography, X-Ray Computed","Radiotherapy, Image-Guided"],"sdg_mappings":[{"sdg_number":3,"sdg_label":"3.
