Material and Methods: The authors created one field with an \"optimal fluence\" of intensity 1.0 (full dose) and one field with intensity 0.0 (no dose) in the central part of the field. The influence of different dose rates (DRs) and maximum leaf speeds (LS) on the calculated and measured dose and dose profiles were analyzed. Results: Good agreement between calculated and measured dose in the case of a field of intensity 1.0 was found. For the field with intensity 0.0, the measured dose was 20-60% tower than the dose calculated by the \"actual fluence\". The results were found dependent on the DR and LS. Conclusion: The overestimation in regions of optimal intensity 0.0 by the planning system cannot be resolved by the user. Taking the measured dose in the region of desired intensity 1.0 and other technical limitations (like beam hold interrupts or spikes in the cross and longitudinal profiles) into consideration, the application of an LS of 2.5 cm/s and a DR of 500 MU/min is recommended in order to minimize radiation dose applied to organs at risk, which are located in regions of low intensity, like, for example, the spinal cord."],["dc.identifier.doi","10.1007/s00066-009-2028-2"],["dc.identifier.isi","000272525100007"],["dc.identifier.pmid","20013092"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/55861"],["dc.notes.status","zu prĂĽfen"],["dc.notes.submitter","Najko"],["dc.publisher","Urban & Vogel"],["dc.relation.issn","0179-7158"],["dc.title","Overestimation of Low-Dose Radiation in Intensity-Modulated Radiotherapy with Sliding-Window Technique"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The measurement method of the secondary standard of the Physikalisch-Technische Bundesanstalt had to be slightly modified in order to be able to measure inside a Foley catheter. The absorbed dose to water response of the alanine dosimetry system to 192Ir was determined with a reproducibility of 1.8% relative to Co-60. The resulting uncertainty for measurements inside the urethra was estimated to be 3.6%, excluding the uncertainty of the dose rate constant Lambda. The applied dose calculated by a treatment planning system is compared to the measured dose for a small series of Ir-192 HDR irradiations in a gel phantom. The differences between the measured and applied dose are well within the limits of uncertainty. Therefore, the method is considered to be suitable for measurements in vivo."],["dc.identifier.doi","10.1088/0031-9155/54/9/022"],["dc.identifier.isi","000265350300022"],["dc.identifier.pmid","19384000"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/16786"],["dc.notes.status","zu prĂĽfen"],["dc.notes.submitter","Najko"],["dc.publisher","Iop Publishing Ltd"],["dc.relation.issn","1361-6560"],["dc.relation.issn","0031-9155"],["dc.title","In vivo dosimetry in the urethra using alanine/ESR during Ir-192 HDR brachytherapy of prostate cancer-a phantom study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
