The reproducibility during radiotherapy of head and neck tumors has been significantly improved by special devices like individual masks. However, the temporary fixation of head and neck region to the irradiation berth induces in many patients anxiety state and reduces this way the compliance. By means of modification of the device used till now a new model in which the set up mask is only coupled to the berth, could be developed. The clinical evaluation showed that this form of fixation device is much better tolerated by the patients and can be adapted without any problems to all equipment pieces in a radiotherapy department. The estimated reproducibility was comparable to that obtained with mounted device. The average translation of the central beam during 21 days observation period was 2.6 +/- 1.4 mm (0 to 9 mm) in the sagittal plane and 3.4 +/- 1.0 mm (1 to 8 mm) in the frontal plane.
像个体化面罩这样的特殊装置显著提高了头颈部肿瘤放疗期间的重复性。然而，头颈部区域在放疗床的临时固定会使许多患者产生焦虑状态，从而降低了依从性。通过对现有使用装置进行改进，开发出了一种新模型，其中固定面罩仅与放疗床相连。临床评估表明，这种固定装置患者的耐受性要好得多，并且可以毫无问题地适配放疗科的所有设备。估计的重复性与使用固定装置时相当。在21天的观察期内，中心束在矢状面的平均平移为2.6±1.4毫米（0至9毫米），在额状面为3.4±1.0毫米（1至8毫米）。
