| 目的 建立一个基于SPECT功能图像的肝脏虚拟手术评估系统。方法 在VC++环境下,用MITK作为算法平台,对肝脏SPECT断层图像进行三维表面绘制;在绘制结果上交互式添加控制点,利用控制点插值生成切割曲面。结果 在实现三维表面绘制的基础上,仅利用二维输入输出设备,实现任意曲面切割的虚拟手术设计,可以计算虚拟手术前后的肝功能。结论 本系统可以应用于肝脏SPECT虚拟手术及术前肝功能评估,从而减小手术风险。 |

| Objective To build a liver virtual surgery evaluation system based on SPECT images. Methods The system was developed under VC++ programming environment with the help of MITK, and the clipping surface was made using the control points on the three-dimensional rendering of the SPECT images of the liver. Results This research focused on the clipping algorithm on the basis of three-dimensional surface rendering, and achieved arbitrary clipping which made the virtual surgery more accurate, only using traditional two-dimensional input and output devices. With this innovative method, liver function could be calculated after the virtual surgery. Conclusion The results demonstrate that this system is possible to be applied not only in liver SPECT virtual surgery, but also in liver function evaluation before surgery, therefore reduces surgery risk. |
