摘要：

背景：CT扫描所得DICOM数据在Mimics软件中的运用是目前国际上公认的计算机辅助手术的“金标准”。
目地：探索一条可行的计算机辅助手术途径。
方法：将骨盆肿瘤病例CT扫描图像数据导入Mimics10.01软件，三维重建包含髂血管的全骨盆几何模型,并按Enneking and Dunhan提出的标准分型，该病例为TypeⅡ型。利用mimics软件的三维重建全骨盆几何模型的各项数据进行术前测量，设计肿瘤切除范围，并进行模拟肿瘤切除假体置换。
结果与结论：利用mimics软件重建的全骨盆三维几何模型可准确反映骨盆的三维立体结构和预测肿瘤的大小，并可进行任意旋转观察，精确测量出相关的各项指标。为定制假体提供有意义的参考数据，有效实现了骨盆肿瘤广泛切除特制假体置换术的模拟。结果提示Mimics软件重建的包含髂血管的全骨盆几何模型可立体直观显示骨盆内部解剖结构并明确肿瘤分型。Mimics可以为术前设计和手术模拟提供快捷、便利、精确、可重复运用的模型。

Abstract:

BACKGROUND: CT scan DICOM data from the use of Mimics software is the internationally recognized “gold standard” of computer-assisted surgery.
OBJECTIVE: To investigate a viable means of computer assisted surgery.
METHODS: CT Dicom format image of one case of pelvic tumors was imported into Mimics 10.01, three-dimensional reconstruction of the geometry model of total pelvis was performed including iliac artery. According the standard classification of Enneking and Dunhan, the case was type Ⅱ. All data from mimics three-dimensional reconstruction of the geometry model of total pelvis were used for preoperative measurements, surgical simulation in extensive resection of pelvic tumor and prostheses replacement surgery.

RESULTS AND CONCLUSION: The results showed that by using the mimics, the three dimensional geometric model of total pelvis accurately reflected the structure of pelvis and predicted the tumor size, and could be rotated to benefit observation, measured every parameter accurately needed in the operation, provide useful data for custom-made acetabular prostheses and effectively realized surgical simulation in extensive resection of pelvic tumor and prostheses replacement surgery. The 3D reconstruction of geometry model of the total pelvis including the iliac artery using mimics can clearly display the pelvis internal anatomic structure and type the tumor, therefore providing a fast, convenient, precise, repeatable application model for preoperative planning and simulation.
