The effect of altering these limitations on the number of monitor units and radiation dose to the organs at risk (OAR) were analysed. Methods: IMRT plans for different LVs from 1.0 cm/sec to 10.0 cm/sec and different DRs from 100 MU/min to 600 MU/min for two patients with prostate cancer and two patients with squamous cell cancer of the scalp (SCCscalp) were calculated using the same \"optimal fluence map\". For each field the number of monitor units, the dose volume histograms and the differences in the \"actual fluence maps\" of the fields were analysed. Results: With increase of the DR and decrease of the LV the number of monitor units increased and consequentially the radiation dose given to the OAR. In particular the serial OARs of patients with SCCscalp, which are located outside the end position of the leafs and inside the open field, received an additional dose of a higher DR and lower LV is used. Conclusion: For best protection of organs at risk, a low DR and high LV should be applied. But the consequence of a low DR is both a long treatment time and also that a LV of higher than 3.0 cm/sec is mechanically not applicable. Our recommendation for an optimisation of the discussed parameters is a leaf velocity of 2.5 cm/sec and a dose rate of 300-400 MU/min (prostate cancer) and 100-200 MU/min (SCCscalp) for best protection of organs at risk, short treatment time and number of monitor units."],["dc.identifier.doi","10.1186/1748-717X-3-31"],["dc.identifier.isi","000260418200001"],["dc.identifier.pmid","18811954"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/4321"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/53311"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Biomed Central Ltd"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Impact of different leaf velocities and dose rates on the number of monitor units and the dose-volume-histograms using intensity modulated radiotherapy with sliding-window technique"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The purpose of this study was to develop a patient related treatment plan verification protocol using a two dimensional ionization chamber array (MatriXX, IBA, Schwarzenbruck, Germany). Method: Measurements were done to determine the dependence between response of 2D ionization chamber array, beam direction, and field size. Also the reproducibility of the measurements was checked. For the patient related verifications the original patient Rapid Arc treatment plan was projected on CT dataset of the MatriXX and the dose distribution was calculated. After irradiation of the Rapid Arc verification plans measured and calculated 2D dose distributions were compared using the gamma evaluation method implemented in the measuring software OmniPro (version 1.5, IBA, Schwarzenbruck, Germany). Results: The dependence between response of 2D ionization chamber array, field size and beam direction has shown a passing rate of 99% for field sizes between 7 cm x 7 cm and 24 cm x 24 cm for measurements of single arc. For smaller and larger field sizes than 7 cm x 7 cm and 24 cm x 24 cm the passing rate was less than 99%. The reproducibility was within a passing rate of 99% and 100%. The accuracy of the whole process including the uncertainty of the measuring system, treatment planning system, linear accelerator and isocentric laser system in the treatment room was acceptable for treatment plan verification using gamma criteria of 3% and 3 mm, 2D global gamma index. Conclusion: It was possible to verify the 2D dose distribution and MU of Rapid Arc treatment plans using the MatriXX. The use of the MatriXX for Rapid Arc treatment plan verification in clinical routine is reasonable. The passing rate should be 99% than the verification protocol is able to detect clinically significant errors."],["dc.identifier.doi","10.1186/1748-717X-6-21"],["dc.identifier.isi","000288098400001"],["dc.identifier.pmid","21342509"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/5926"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/23825"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Biomed Central Ltd"],["dc.relation.issn","1748-717X"],["dc.rights","CC BY 2.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.0"],["dc.title","Two years experience with quality assurance protocol for patient related Rapid Arc treatment plan verification using a two dimensional ionization chamber array"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The treatment plans were compared with each other using dose-volume histograms Results The 3D conformal technique showed a good PTV coverage. if PTV was distant to organs at risk (OAR). If PTV was nearby OAR, the 3D technique revealed a poor PTV coverage in contrast to both intensity-modulated techniques The conventional IMRT technique showed a slightly better PTV coverage than RapidArc The advantages of RapidArc were a shorter treatment time, less monitor units and a small V(107%) Conclusions: If PTV is distant to OAR. the use of 3D conformal technique is sufficient. Otherwise an intensity-modulated technique should be used RapidArc was faster than conventional IMRT and should be preferred if PTV coverage is adequate (C) 2009 Elsevier Ireland Ltd All rights reserved Radiotherapy and Oncology 93 (2009) 593-596"],["dc.identifier.doi","10.1016/j.radonc.2009.10.002"],["dc.identifier.isi","000272762900037"],["dc.identifier.pmid","19897266"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6277"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/55855"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Elsevier Ireland Ltd"],["dc.relation.issn","0167-8140"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Radiotherapy of malignant gliomas: Comparison of volumetric single arc technique (RapidArc), dynamic intensity-modulated technique and 3D conformal technique"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

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.

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 prüfen"],["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"]]
