首例中国可视化人体头颈部CT影像三维重建的初步研究

A preliminary study of CT 3-D reconstruction of head and neck region of the first Chinese visible human

目的 对首例中国可视化人体头颈部CT影像进行三维重建研究。方法 将首例中国可视化人体头颈部的轴位断层CT图像 (层厚 1mm ,连续扫描 ) ,应用SiemensCRT3 .0图像处理软件在SGIGraphics计算机工作站上进行三维重建和观察。结果 头面部结构得到良好重建 ,其面部轮廓包括鼻翼、唇、外耳廓、下颏等均能清晰显示。头颈部骨骼的精细三维重建 ,显示出颅底圆孔、卵圆孔、棘孔等细微结构。头颈部三维剖面观察可使包括垂体、脑干、颈髓、蝶窦、鼻咽等结构获得良好显示。结论 本研究实现了对首例中国可视化人体头颈部CT影像的三维重建和可视化 。

Objective To obtain the CT image 3 D reconstruction of head and neck region of the first Chinese visible human. Methods The CT data of head and neck region of the first Chinese visible human were processed with Siemens 3 D Virtuoso VA(R2.6) software in SGI Graphics Computer Workstation. The 3 D reconstruction of head and neck surface and skeletal structure were carried out and studied. Results The face and neck were well reconstructed. The nose, lips, ears and chin could be clearly shown. The skeletal structures in the head and neck region were fairly reconstructed and displayed very well and even the fine structures in skull base such as foraman ovale and foramen spinosum could be seen. Many anatomic structures such as pituitary gland, brain stem, cervical marrow, sphenoid sinus, nasopharynx could be displayed in detail on the 3 D reconstruction section. Conclusion This study has realized the CT image 3 D reconstruction and visualization of head and neck region of the first Chinese visible human and provided morphologic data for further studies of 3 D structures, comparative studies of anatomy and imaging of the head and neck.
