An accuracy of +/- 1 mm in surgical localization of brain targets was reliably attained with a new sonar-operated system, provided that air turbulence was minimized. Since a conventional frame construction with coordinate settings has been disposed of, apart from a halo ring head holder, free access to the operating site is guaranteed. Using offset probes, measurements in depth can be realized with a relatively simple hardware arrangement. A small, 'floating' locator probe can be attached to all kinds of surgical instruments; its spatial position is computed in real time and immediately referred to computed tomography/magnetic resonance imaging scans. Although this work is still in progress, promising applications both in stereotactic and in open surgery are envisaged.
一种新的声纳操作系统在脑靶点手术定位中可靠地实现了±1毫米的精度，前提是将空气湍流降至最低。由于除了一个光环式头架外，已经摒弃了带有坐标设置的传统框架结构，因此保证了对手术部位的自由 access。使用偏移探头，可以通过相对简单的硬件配置实现深度测量。一个小型的“浮动”定位探头可以连接到各种手术器械上；其空间位置实时计算，并立即参考计算机断层扫描/磁共振成像扫描。尽管这项工作仍在进行中，但设想了在立体定向手术和开放手术中的有前景的应用。
