目的应用CAD技术开发建立乳房三维重建及乳房体积测量的系统软件,指导临床乳房癌术后一期乳房再造的术前设计。方法收集2006年1月至2007年12月间的16例乳腺MRI检查的影像学资料,数据以医学数字成像和通信标准文件格式刻输出。应用VTK、ITK、FLTK等C++6.0程序软件编程技术进行乳房三维重建及体积测量。结果(1)开发建立了乳房再造计算机辅助设计系统;(2)通过计算机编程进行乳房边界的界定,完成了乳房三维重建;(3)在重建乳房三维立体图像的基础上,通过计算各层面及其厚度和体积,再将各层体积叠加计算出乳房体积。结论应用CAD系统三维重建乳房,具有双侧对称度高,美观、逼真的优点;应用CAD系统测量乳房体积技术精确度高,测算速度快;CAD系统乳房三维重建及乳房体积测量软件有助于乳房一期再造的术前设计。

Objective To develop a design system to measure the volume of the breast by using of 3-Dimensioned computer assisted design and to aid the preoperative design of autologous breast reconstruction. Methods From January 2006 to December 2007, breast MRI data were collected in 16 patients and outputted with the standard file format of digital imaging and communications in medicine (DICOM). Application of C++ 6.0 program technology such as VTK (Visualization Toolkit) and ITK (Insight Toolkit) were used for 3-Dim...
