Abstract
The diagnostic yield of computed tomography (CT)-guided biopsies is dependent on accurate needle insertion. A laser-assisted angle selection system was custom fabricated and used during a CT-guided lung biopsy. Off-target error was measured comparing standard methods to the laser method while pointing towards the target from the skin. The difference between the planned angle and selected angle using the laser-assisted system was 2°, improved from 12° with the standard method. Although yet to be confirmed, laser-assisted angle selection systems may improve the accuracy of needle placement, which may translate into improved outcomes for certain needle based procedures.
摘要
计算机断层扫描（CT）引导下活检的诊断率取决于准确的进针。在 CT 引导下肺活检中定制并使用了激光辅助角度选择系统。从皮肤向目标点进针时，通过比较标准方法和激光方法测量非靶向误差。使用激光辅助系统选择的角度与计划角度之间的差异为 2°，优于标准方法的 12°。尽管尚未得到证实，但激光辅助角度选择系统可能会提高针放置的准确性，这可能会转化为某些基于针的手术的更好结果。
