A portable and light-weight cephalostat (Porta-Stat) is described. Device design, clinical use, and evaluation to verify accuracy are presented. The basic design uses a mainframe to which the image receptor, head, and X-ray source are referenced for standardization of image and magnification distortion in cephalometric radiographs. In a test to verify the accuracy of image reproducibility, no statistically significant difference was found from a fixed cephalostat system. The Porta-Stat cephalostat has verified accuracy essentially equivalent to traditional cephalometric radiography. Anecdotal case presentations show the usefulness of the Porta-Stat in the dental office, hospital radiology department, and operating room for case documentation, growth monitoring, treatment effect, and clinical research purposes. The device has proved to be useful in the management of TMJ syndrome, orthodontics, oral and maxillofacial surgery, otolaryngology, plastic surgery, neurosurgery, and craniofacial growth monitoring.
本文介绍了一种便携式轻型头颅定位仪（Porta-Stat）。文中展示了该设备的设计、临床应用以及用于验证准确性的评估。其基本设计采用一个主机，图像接收器、头部和X射线源均以此主机为参考，以实现头颅侧位片图像和放大失真的标准化。在一项验证图像再现准确性的测试中，未发现与固定头颅定位系统存在统计学上的显著差异。Porta-Stat头颅定位仪已证实其准确性基本等同于传统的头颅侧位摄影。轶事病例展示表明，Porta-Stat在牙科诊所、医院放射科和手术室中，对于病例记录、生长监测、治疗效果评估及临床研究目的均很有用。该设备已被证明在颞下颌关节综合征管理、正畸、口腔颌面外科、耳鼻喉科、整形手术、神经外科以及颅面生长监测中很有用。
