PC机三维颅颌面影像的建立和应用

Three-dimensional planning on PC environment in craniofacial surgery

目的 在PC上建立颅颌面整形手术的三维CT影像测量和分析系统。方法 应用计算机图像处理技术,在PC机上完成CT标准数据解读,实现颅颌面骨架结构的二维显像和三维重组,并应用于放射性眼眶、眶外伤和下颌角肥大的整形手术治疗。结果 在PC机上重建的三维CT图像信息无损耗,图像清晰,可进行可操作化的测量。结论 PC机三维CT影像测量和分析系统的建立,可以便捷、有效地量化颅颌面手术的术前设计,并为术后判断提供客观依据,提高手术的精确性。

Objective To develop a three-dimensional imaging and analysis system on PC environment in craniofacial surgery. Methods By computer tomography, we developed the software system on PC environment for CT data manipulation and processing, for two and three-dimensional imaging and practical measurement and analysis in the reconstruction of the irradiated enophthalmos, posttraumatic orbital deformity and prominent mandibular. Results It displays more accurate, bright and clear craniofacial skeletal architecture and practical mensuration. Conclusion This development on the PC environment facilitates measurement, visualization and analysis in craniofacial surgery and it can provide objective information for surgical planning and postoperative judgement.
