We have applied the frameless navigation system (StealthStation) to various neurosurgical procedures to examine its usefulness. The system consists of a UNIX based workstation that creates triplanar and 3-dimensional images; an infrared optical digitizer with camera array; a reference-light-emitting diode (LED) array (e.g., reference array); and pointer probe modified by the addition of LEDs. This system was used to assist in placing a minimal skin incision and craniotomy in 4 cases, to determine the tumor/brain interface in 2 cases, to target the subcortical lesion in one case, and to correlate bony structure with a skull base tumor in 3 cases. The combined use with magnetic source imaging of the somatosensory cortex allowed a fast orientation of eloquent areas in 2 cases with peri-Rolandic tumor. This system, thus, was proved to be a useful adjunct to open-tumor biopsy or resection.
我们已将无框架导航系统（StealthStation）应用于各种神经外科手术，以检验其效用。该系统由一个基于UNIX的工作站组成，该工作站可创建三平面和三维图像；一个带摄像头阵列的红外光学数字化仪；一个参考发光二极管（LED）阵列（例如，参考阵列）；以及通过添加LED进行改良的指针式探头。该系统被用于协助4例患者进行最小化皮肤切口和开颅手术，确定2例患者的肿瘤/脑界面，针对1例患者的皮质下病变进行靶向定位，以及在3例患者中将骨结构与颅底肿瘤进行关联。在2例患有罗兰多周围肿瘤的患者中，与体感皮层磁源成像联合使用可实现对明确功能区的快速定位。因此，该系统被证明是开放性肿瘤活检或切除术的有用辅助工具。
