Primary Outcome Measures
NameTimeMethod
<p>The primary endpoint of this study is the actual given dose. The actual given<br /><br>dose is the dose administered to the patient during treatment, taking into<br /><br>account patient positioning accuracy and patient deformations. This actual<br /><br>given dose will in general deviate from the planned dose that was calculated<br /><br>based on the planning CT only. The actual given dose for the two different<br /><br>groups will be calculated and compared to the planned dose. The dose<br /><br>distributions of the following structures will be taken into account:<br /><br>- Gross Tumour Volumes (GTVprimary tumour and GTVlymph node metastases)<br /><br>- Clinical Target Volumes (CTV70 and CTV54.5)<br /><br>- Planning Target Volumes (PTV70 and PTV54.5)<br /><br>- Spinal cord<br /><br>- Parotid glands (ipsilateral and contralateral)<br /><br>- Submandibular glands (ipsilateral and contralateral)<br /><br>- Pharyngeal constrictor muscles (superior, medium and inferior)<br /><br>- Thyroid gland</p><br>
