The reproducibility of a noninvasive computed tomography (CT)/magnetic resonance imaging stereoadapter was tested on 12 healthy volunteers. The adapter was easy to mount and detach without discomfort. Two repeated mountings of the adapter showed a good reproducibility in relation to the scalp. When extrapolated to a hypothetical target in the right thalamus, the mean differences between the two mountings were 0.07 mm in the lateral, 0.16 mm in the anteroposterior and 0.17 mm in the height coordinates. This high degree of reproducibility seems to permit a safe CT-guided functional stereotaxis, where the preoperative CT scanning can take place on one day and the surgery may be performed on any other suitable day.
在12名健康志愿者身上测试了一种非侵入性计算机断层扫描（CT）/磁共振成像立体定位适配器的可重复性。该适配器易于安装和拆卸，且不会引起不适。适配器的两次重复安装在与头皮的关系上显示出良好的可重复性。当外推到右侧丘脑的一个假设靶点时，两次安装之间在横向坐标上的平均差异为0.07毫米，在前后坐标上为0.16毫米，在高度坐标上为0.17毫米。这种高度的可重复性似乎允许进行安全的CT引导功能立体定向，即术前CT扫描可以在一天进行，手术可以在任何其他合适的日子进行。
