    摘要:

    骨组织模型的精确 3D 打印对骨科手术前进行手术方案规划、术中定位和术后评估手术效果均 有不可替代的作用。然而,打印等比例的、与患者完全匹配的、精确的骨组织模型涉及术前 CT 影像扫 描、3D 建模、3D 打印及打印后处理一系列流程。其中,对于 3D 打印前的重建,CT 扫描图像序列的选择直接影响打印模型的质量。通过比较骨窗序列和标准序列 CT 图像的建模及打印结果可知,后者的模型质量优于前者,表明骨组织模型并非一定要采用骨窗序列。该研究为骨组织模型的精确 3D 打印和 建模在 CT 图像序列选择阶段的决策提供了科学依据。

    Abstract:

    3D printed bone tissue model is important to the pre-operation planning, precision intraoperative location and post-surgery assessment. However, to print the same scale bone tissue model of patients depends on a series of processing from the CT image scanning, 3D reconstruction, 3D printing to post processes of the printed model. In the process, the quality of CT images and 3D reconstruction directly affects the precision and quality of the 3D printed model, especially the selection of which CT image series is a key problem that needs to be answered. Through the comparison of 3D reconstruction results between the bone series and stand series of CT images shown that the standard series produce better quality than the bone series. The conclusion is that the standard series may produce reconstructed 3D model of bone tissue in a better way than the bone series. And the conclusion provides a scientific proof for the selection of CT image series during the 3D reconstruction.
