摘要
目的:研究16排螺旋CT肺脏扫描数据的三维重建方法和肺切除的可视化仿真手术效果。材料与方法:采集肺脏16排螺旋CT的原始扫描数据,采用自行研发的图像处理软件对分割后的图像进行三维重建,再将重建后的数据导入FreeForm Modeling System中进行修饰、平滑处理,利用GHOST SDK软件开发出各种仿真手术器械,利用PHANTOM力反馈设备进行肺切除术前的可视化仿真手术研究。结果:三维重建出来的图像结构清晰,可真实再现肺脏和周围重要器官及管道的结构;仿真肺切除手术精确逼真、形象生动,且能一定程度上感受在手术台上直接操作的感觉,沉浸感强,交互性好,效果满意。结论:肺脏的三维重建和可视化仿真手术可以让术者在手术前对肺脏周围的三维解剖结构有清晰的了解,对降低手术风险、减少手术并发症、提高手术效果有很大的帮助。
Purpose:To study the three-dimensional(3D) reconstruction of pancreas based on the data of 16-row helical CT scanning and the effect of the dynamic simulation surgery of lung.Materials and Methods:The original scan data of spleen 16-slice helical CT were collected.Then the image processing software was used to proceed with the 3D reorganization with the images which are segmented.Import reconstructed objectives to Freeform Modeling System were embellished and smoothed.GHOST SDK software of Freeform Modeling System was utilized to develop various instruments needed by simulated surgeries.And the visualization of simulated surgery by PHANTOM software was studied before the pneumonoresection.Results:The image procedure could be calculated soon and efficiently.The clear picture structure of 3D-reorganization was an exact reproduction of lung and the structures of vital organs and passages around;The simulated pneumonoresection was high simulated,vivid,exact and the operator could feel like a real surgery.Conclusion:The research of 3D reorganization and visual artificial simulation surgery to lung make surgeons know the 3D anatomical structure around lung clearly before the surgery.And it is of great help to reduce the risk of surgery,decrease operative complications,and improve the effect of surgery.
