A stereotactic device was developed to facilitate CT- or MR-guided punctures of the body. The correct needle angulation is checked by the reflection of fan-shaped red and green laser beams upon the needle. Due to its principle of function and design the device has considerable advantages: The puncture angle can be controlled in three dimensions. The freedom of movement within the operation area will not be affected. The device does not have to be permanently installed and can be employed in MRI at any field strength. Furthermore, all kinds of puncture instruments can be used.
开发了一种立体定向装置，以方便在CT或MR引导下对身体进行穿刺。通过扇形红绿光激光束在针上的反射来检查针的正确角度。由于其功能原理和设计，该装置具有相当大的优势：穿刺角度可以在三维空间内控制。操作区域内的活动自由度不会受到影响。该装置不必永久安装，可在任何场强的MRI中使用。此外，可以使用各种穿刺器械。
