We developed a new headholder for the fixation and repositioning of patient head in PET study. The device consists of acryl frame and headrest of thermoplastic resin. Special gel is placed on the headrest to adapt different shape of occipit a in each patient. Individual face mask was made with thermoplastic resin just before the PET study and was fixed with the holder using plastic taper. It took about 2-3 min to fix the patient head using these system. Immobilization of the patient's head during PET study was good. Accuracy of repositioning in the same patient was relatively good between separate PET studies.
我们开发了一种用于在PET研究中固定和重新定位患者头部的新型头架。该装置由丙烯酸框架和热塑性树脂头枕组成。头枕上放置特殊凝胶以适应每位患者不同形状的枕部。在PET研究前，用热塑性树脂制作个体面罩，并使用塑料锥度将其与头架固定。使用这些系统固定患者头部大约需要2 - 3分钟。PET研究期间患者头部的固定效果良好。在不同的PET研究之间，同一患者重新定位的准确性相对较好。
