This fact shows that any uncorrected deviation of a patient from its initial position as recorded during simulationwill undoubtably impact the surrounding OARs. RESULTS Quantification of patient set-up errors and definition of margins The number and age of the treated patients during the —12 time interval are shown in Figure 2.

Geometric uncertainties in radiotherapy : defining the planning target volume

Some features of WorldCat will not be available. Success of satellites and remote working in radiotherapy — 27 and 28 September in London. Dosimetric impact of patient set-up errors on dose planning After having quantified the uncorrected set-up errors using MOSAIQ and EPID images, their dosimetric impact on the dose distributions was assessed.


The assessment has taken into account the cases when patient set-up errors occur. This study is similar to the study by Mavroidis et al.

Hypofractionated intensity-modulated radiotherapy 70 Gy at 2. Overall there is some evidence that they tend to radiktherapy, but that similar levels should be achievable. Inclusion of geometrical uncertainties in radiotherapy treatment planning by means of coverage probability.

The E-mail Address es field is required. This expression overcomes the limitations of all survival models in order to generalize the application of EUD concept to normal structures and tumours. radiotheraoy

The medium age is Geometric uncertainties in radiotherapy: This study was carried out on a sample of 20 patients treated for nasopharyngeal cancer between and in the radiation—oncology centre of HCA.

As an introductory offer, there would be no article processing charges for the first few months. Prescribing, recording and reporting photon beam therapy.

Strbac B,Jokic VS. Patients were imaged weekly and whenever the therapist thought there might be a problem. 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. Br J Radiol ; 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.

Changes in early and late radiation responses with altered dose fractionation: A total prescribed dose of Bur planned or under consideration: This would therefore require finding an alternative method for taking set-up errors into account in this case. Nasopharyngeal cancer is common in North Africa, especially in Algeria.

Several special editions were in process including: In the second part of this study, we have shown that set-up errors in the clinical situation have an impact on the gEUDs received by targets and by critical structures in 3D-CRT nasopharynx treatment.
