摘要
目的基于人体胃-食管结构的CT图像进行3D建模,提供胃-食管正常形态及反流形态的3D模型。方法基于胃-食管结构CT图像,利用Mimics 10.01,Geomagic Studio 2012和SolidWorks 2018软件进行3D建模。其中,使用Mimics软件对模型进行粗分割与细分割,导出胃-食管点云数据;在此点云数据的基础上,使用Geomagic Studio软件对模型进行精简与修补,并完成填充孔洞、光滑曲面等操作,得到较为完整的胃-食管3D模型;最后将3D模型导入到SolidWorks中,处理贲门处结构并建立胃-食管正常模型及贲门病变模型。使用软性3D打印技术对模型进行加工。结果所建立的胃-食管模型的各项几何参数均在实际范围内,模型具有一定的实用性。结论该模型可以作为胃外科手术模拟训练的基础材料,帮助医生或医学学生熟练并提高胃外科手术的操作技巧与手术水平。
Objective To perform 3D modeling based on CT images of human stomach-esophagus structure and provide 3D models of normal and reflux forms of gastroesophagus.Methods Based on CT images of stomach-esophagus structure,3D models was established using Mimics 10.01,Geomagic Studio 2012 and SolidWorks 2018 software.In the modeling process,the Mimics software was used to coarsely and finely divide the model to export stomach-esophageal point cloud data.On the basis of the point cloud data,Geomagic Studio software was used to simplify and repair the model,and complete the operations of filling holes and smooth surfaces.SolidWorks software was used to process the structure of the cardia and establish a normal model of stomach-esophagus and a model of cardiac disease.Finally,the model was replicated using soft 3D printing technology.Results The geometric parameters of the established stomach-esophagus model were within the actual range,which proved that the model has certain practicality.Conclusions The model can be used as a basic material for gastric surgery simulation training,to help doctors or medical students to be proficient and improve the operation skills and surgical level of gastric surgery.
