应用螺旋CT三维重建颌面部软组织的研究

The research on 3-D maxillofacial soft tissue reconstruction by spiral CT

目的:评价螺旋CT在颌面部软组织重建中的价值。方法:对1例右耳缺损患者的头部进行螺旋CT扫描,扫描数据以DICOM格式储存。在诊断工作站上以SSD法对图像进行重建。结果:螺旋CT能一次快速精确完成整个头部的扫描与重建,面部软组织、器官重建图像清晰,但瞳孔位置不能显示。结论:对于头面部除瞳孔以外的软组织三维重建,可选择螺旋CT三维重建方式。

PURPOSE： To evaluate the role of spiral CT in 3-D reconstruction of maxillofacial soft tissues. METHODS： Spiral CT was given to a patient who had his right ear absent. The data was recorded in DICOM format. Digital image was reconstructed on GE advantage workstation in SSD way. RESULTS： Spiral CT can quickly and precisely scan and reconstruct the whole head, the reconstructed images of facial soft tissues and apparatus were very clear, but the site of pupil can not display. CONCLUSION： Except for the pupils, spiral CT is a useful way for maxillo-facial soft tissue reconstruction. It can be widely used in hospitals.
