In order to maintain good communication between the optical tracking system and image-based surgical navigation software through the serial port, we developed a serial communication software by calling the WinAPI function with Visual C++ 6.0. We then completed the data reading, integration and analysis. We further calculated the relative position between the surgical instruments and the patient coordinate system, realized the registration between the CT model data and the spatial location of patient by using ICP algorithm, and finally achieved real-time tracking surgical instruments on the surgery. The practical effects of clinical surgery have proved that this system has good robustness, real-time property and reliability, which can meet the requirements of clinical surgery.
为了通过串口保持光学跟踪系统与基于图像的手术导航软件之间的良好通信，我们使用Visual C++ 6.0调用WinAPI函数开发了一个串口通信软件。然后我们完成了数据读取、整合与分析。我们进一步计算了手术器械与患者坐标系之间的相对位置，利用ICP算法实现了CT模型数据与患者空间位置的配准，最终在手术中实现了对手术器械的实时跟踪。临床手术的实际效果证明，该系统具有良好的鲁棒性、实时性和可靠性，能够满足临床手术的要求。
