To study the three-dimensional (3D) reconstruction and the visualization simulation surgery of spleen based on the scanning data of 64-slice helical computed tomograph (CT).
The original data of 64-slice helical CT of spleen was collected, and then the CT image sequences were segmented and automatically extracted using auto-adapted region growth algorithm, and were conducted with the segmented images by adopt self-developed image processing software for 3D reconstruction. Finally, the 3D models were imported into FreeForm Modeling System for modifying and smooth. And the visualization simulation surgery was performed before splenectomy.
It was fast and effective to utilize auto-adapted region growth algorithm to conduct spleen image program segmentation; the reconstructed models were seen clearly and could reappear the structure of the spleen and the important surrounding organs. The effect of the splenectomy simulation surgery was similar to the practical surgery.
The research on 3D models of spleen and visualization simulation surgery of splenectomy could lead to clinical benefits. It maybe improve the surgical effect and decrease the surgical risk and reduce the complication demonstrating visualized operation before surgery.
基于64层螺旋计算机断层扫描(CT)的扫描数据研究脾脏的三维(3D)重建及可视化模拟手术。
收集脾脏的64层螺旋CT原始数据,然后采用自适应区域生长算法对CT图像序列进行分割并自动提取,通过自行开发的图像处理软件对分割后的图像进行3D重建。最后,将3D模型导入FreeForm Modeling System进行修改和平滑处理。并在脾切除术前进行可视化模拟手术。
利用自适应区域生长算法进行脾脏图像程序分割快速有效;重建模型清晰可见,能够重现脾脏及周围重要器官的结构。脾切除模拟手术效果与实际手术相似。
脾脏3D模型及脾切除可视化模拟手术的研究具有临床应用价值。它可能提高手术效果,降低手术风险,减少并发症,术前展示可视化操作。
