Events planned or under consideration: Geometgic should breathing motion be combined with others errors when drawing margins around clinical target volume?

Current achievements in oncology Rep Pract. Geometrical uncertainties, radiotherapy planning margins, and the ICRU report. A working party, led by Sam Tudor, had been put together to write an addendum to the BIR report on geometric uncertainties in radiotherapy. Evaluation of set-up errors in head and neck radiotherapy using electronic portal imaging.

Bentzen SM Steepness of the radiation dose-response curve for dose-per-fraction escalation keeping the number of fractions fixed Acta. Systematic error was calculated as the average deviation of a particular reference structure between simulation and treatment and is given by: A proposal for the reduction of systematic patient set-up errors with minimal portal imaging workload. The one exception is where there is significant lung involvement, where it is likely that uncertainties have now improved due to widespread use of more accurate heterogeneity models.

The specific requirements or preferences of your reviewing publisher, classroom teacher, institution or organization should be applied. Indeed, calculations are based on radiobiological models that can explicitly optimize the trade-offs that radiotherappy be made between eradicating the tumour and avoiding damage to healthy surrounding tissue. The BIR was already looking at the programme for and ideas for topics and speakers would be welcomed.

The overall aim of the Oncology and Radiotherapy Special Interest Group is to promote and facilitate teaching and research in clinical oncology and related professions. The name field is required. Thwaites DI Verification and external audit of dose for conventional radiotherapy and the new technology: If gelmetric portal images PIs were incorrect, the patient position was corrected within the mask and the additional PI was performed to recheck the positioning.

It also demonstrated the unavoidable biological impact of patient set-up errors on tumours and OARs when they were not corrected, especially in the case of the optic nerves and brainstem.
