To evaluate mechanical registration in a stereotactic system with framework neurosurgery navigation, setting scalp markers as the mutual frame of reference.
The system can automatically convert the coordinates of the stereotactic device and CT or MRI images, and realize computer-assisted neurosurgery by the stereotactic system (framework neurosurgery navigation). We set targets in the skull; seven patients were operated on by open-skull stereotactic neurosurgery for clinical trials. Three cases were operated on by this method; the other four cases were treated by this method and the ASA620S operation plan system at the same time as a comparison.
The targets were accurately located in seven patients. Four patients underwent the two different localization methods; the probe directed equally accurately (vector error: 3.96+/-1.90 vs. 3.26+/-1.22, P=0.06>0.05, paired t-test). All surgical procedures were successful.
Framework neurosurgery navigation has equal localization accuracy compared with the traditional stereotactic device. Framework neurosurgery navigation does not require installation of a stereotactic framework before imaging or narcotic intubation; this differs from the traditional stereotactic technique. It can alleviate patient suffering, shorten preparation time, benefit anesthesia, and aid patient positioning during surgery.
以头皮标记物作为相互参照框架，评估立体定向系统中框架神经外科导航的机械配准。
该系统可自动转换立体定向设备与CT或MRI图像的坐标，并通过立体定向系统（框架神经外科导航）实现计算机辅助神经外科手术。我们在颅骨上设置靶点；7例患者接受了开颅立体定向神经外科手术以进行临床试验。3例采用该方法进行手术；另外4例同时采用该方法和ASA620S手术计划系统进行治疗以作比较。
7例患者的靶点均准确定位。4例患者接受了两种不同的定位方法；探针指向同样准确（矢量误差：3.96±1.90对3.26±1.22，P = 0.06>0.05，配对t检验）。所有手术均成功。
框架神经外科导航与传统立体定向设备相比具有同等的定位准确性。框架神经外科导航在成像或麻醉插管前无需安装立体定向框架；这与传统立体定向技术不同。它可减轻患者痛苦，缩短准备时间，有利于麻醉，并有助于手术期间患者的体位摆放。
