摘 要:目的:应用冷冻数控铣削技术获取颞骨标本的薄层断面解剖数据。方法:选择2例4侧国人成年尸体颞骨标本,先使用多层螺旋CT扫描,再经明胶包埋和深低温冷冻后用数控铣床制成层厚为0.1mm的耳颞部连续横断面,数码相机摄影,计算机保存数据,然后与同一标本的CT图像进行对照。结果:2例标本分别获得259幅和265幅层厚为0.1mm的横断层图像,颞骨的重要解剖结构及其毗邻关系都得到良好显示,与调整角度后的CT图像达到完全一致。结论:应用冷冻数控铣削技术获取的颞骨薄层断面图像,不仅能很好地与多层螺旋CT薄层图像相匹配,而且为颞骨的三维可视化奠定了基础。Objective: To obtain the sectional data of the temporal bone using computerized cryomilling technique. Methods: To collect 2 head specimens of Chinese adults, after examining the temporal bone with multi-slice spiral CT, embedding with galetin and freezing under profound hypothennia, the specimens were sliced into 0. 1 mm continuous sections on transversal plane with the computerized miller, and take photographs with digital camera, save the data in computer, then compare with the same specimens images. Rsults:2 head specimens were sliced into 259 and 265 continuous sections of 0.1 mm on transversal plane. The thin sections of the temporal bone can clearly delineate the anatomical details of the temporal bone and their relationships, the same specimens images postprocessed by multiplanar reformation(MPR) came to coincidence completely with these sections. Conclusion: The thin sectional images of the temporal bone obtained by computerized milling technique can matching with the CT images, and will be the base of three demensional reconstruction of the temporal bone.
