Laser guidance facilitates needle alignment in-plane to the ultrasound beam. Once the ultrasound image is optimized, there is no further need to maneuver the probe. Therefore, we designed a laser mount probe holder prototype, and examined the ease of visualization of the needle tip using the laser mount probe holder. The needle brightness was quantitatively measured using an image analysis software. We found that the laser mount probe holder is useful, not only to visualize the needle tip in the ultrasound plane, but also to fix the best ultrasound image.
激光引导有助于将针与超声束在同一平面内对齐。一旦优化了超声图像，就无需再操作探头。因此，我们设计了一种激光安装探头支架原型，并检查了使用激光安装探头支架观察针尖的便利性。使用图像分析软件对针尖的亮度进行了定量测量。我们发现，激光安装探头支架不仅有助于在超声平面上观察针尖，还有助于固定最佳的超声图像。
