在正电子发射断层扫描(PET)、CT和核磁共振成像过程中，开发了一种用于患者约束和重新定位的新头夹。通过在注射成型的聚苯乙烯外壳和保护乳胶片之间浇注聚氨酯树脂和催化剂，并在树脂固化时将患者的头部放置在模板中，为每个患者制作了定制的模板。当使用交叉激光系统时，头部约束和重新定位达到了很好的效果。重新定位的准确性是通过比较同一患者在不同日期获得的透射式扫描，以及通过比较PET透射式扫描和共面CT扫描来证明的。在CT、PET和核磁共振图像中，没有明显的因头部夹持而产生的伪影。
A new headholder was developed for patient restraint and repositioning during positron emission tomography (PET), CT, and nuclear magnetic resonance (NMR) imaging procedures. A customized form was produced for each patient by pouring polyurethane resin and catalyst between an injection-molded polystyrene shell and a protective latex sheet and placing the patient's head in the form while the resin set. Excellent head restraint and repositioning was achieved when the headholder was used with a crossed-laser system. Repositioning accuracy was demonstrated by comparing transmission scans of the same patient obtained on different days and by comparing PET transmission scans with coplanar CT scans. No artifacts due to the headholder were apparent in CT, PET, and NMR images.
