通过将实时仪器跟踪和原位引导投影直接集成到手持式超声成像探头中，活检等基于针的干预比传统导航系统更容易执行。可以使具有针检测的立体成像足够鲁棒和准确以用作主要导航输入。我们描述了用于超声机的Clear Guide ONE通用导航附件中使用的低成本、易于使用的方法，概述了不同的可用引导方法，并提供了体模试验的准确性结果。
With real-time instrument tracking and in-situ guidance projection directly integrated in a handheld ultrasound imaging probe, needle-based interventions such as biopsies become much simpler to perform than with conventionally-navigated systems. Stereo imaging with needle detection can be made sufficiently robust and accurate to serve as primary navigation input. We describe the low-cost, easy-to-use approach used in the Clear Guide ONE generic navigation accessory for ultrasound machines, outline different available guidance methods, and provide accuracy results from phantom trials.
