胰腺及其周围结构的三维重建研究

目的 建立胰腺及其周围结构三维可视化模型,为胰腺疾病的影像学诊断及外科手术方案选择提供形态学依据.方法 应用中国数字化可视人体数据集,选取从脾上缘至十二指肠下段连续断面图像,对断面图像轮廓进行数据分割,并运用体数据绘制及表面绘制的重建方法,在计算机上对胰、脾外形及其内部管道系统与其毗邻结构进行三维重建和立体显示.结果 重建出了胰腺及其周围结构的三维可视化模型,该模型具有多种显示功能,可显示任意切面的结构,同时也可以任意放大、缩小和任意角度旋转观察.结论 该模型直观揭示了胰、脾及其毗邻区域的三维解剖结构,有助于临床解剖教学以及该区域病变的诊断及手术方案的制定.

Three-dimensional reconstruction of pancreas and its adjacent structures

Objective To build three-dimensional model of the pancreas and peripanercatic organs to provide morphological basis for imaging diagnosis and operation selection of pancreas diseases. Methods Serial cross-sectional images from the first Chinese visible human dataset were reviewed and the structures of pancreas and peripancreatic organs were reconstructed three-dimensionally by using 3D-Doctor software on PC. Results Three-dimensional structures of pancreas and peripancreatic organs were reconstructed successfully. All reconstructed structures could be displayed in multiple methods and color modes. Conclusions The internal and adjacent struc-tures of pancreas can be clearly shown on the reconstructed three-dimensional images. The visible model is a useful reference both for clinical diagnosis and surgical practice.
